This is a bug report for perl from ***@shlomifish.org,
generated with the help of perlbug 1.39 running under perl 5.16.3.

Threaded perl-5.18.0 fails the re/pat_rt_report_thr.t test script on
Mageia Linux 3 i586 (32-bit x86 - NOT x86-64). To reproduce, use Mageia Linux
3 and either of the following build files:

#!/bin/bash

# This script reproduces a failure at the "make test" stage with perl-5.18.0
# on i586 Mageia Linux 3 (and Mageia Linux Cauldron).
#
# To reproduce do:
# tar -xvf perl-5.18.0.tar.bz2.
# cd perl-5.18.0.
# bash ~/build-perl-on-i586-with-failure/build-perl-with-failure.bash
# make
# make test

# Based on the Mageia's perl-5.18.0-1's .src.rpm's .spec.

I built with these arguments on dromedary and all tests passed. Now,
dromedary is x86_64; I don't have a Linux 586 available.

That suggests that the test failures you witnessed are specific to the

I would recommend trying other builds on this system, adding one
argument at a time until the failing tests emerge.

Thank you very much.

I built with these arguments on dromedary and all tests passed. Now,
dromedary is x86_64; I don't have a Linux 586 available.
The fact that it fails on i586 was the whole point. All tests are
successful on x86-64 with the same configuration.

Can't you set up an i586 Linux VM? See https://www.virtualbox.org/ .

Yes, maybe.

Yes, I already reduced the flags considerably and I will reduce them

I was able to reproduce it on Mageia Linux 3 i586 with this:

Is there a need for further reduction?

Would it be possible for you to set up a Mageia 3 32-bit i586 VM so you can
debug it? You can download a CD .iso from http://www.mageia.org/en/downloads/ -
the dualarch or the LiveCD KDE/LiveCD GNOME will do. Is there anything else I

Have you tried contacting someone with a vested interest in having
perl work on
Mageia? Specifically, the Mageia community?
Well, I am part of the Magiea community - being a packager for them and
helping with other things I can, and reported this bug on behalf of
Jerome Quelin and Olivier Blin and other packagers who discovered this
bug, as I was able to reproduce it. And we don't know exactly how to
start debugging this bug, so we are asking your for help. It may be
caused by a new glibc version or may be a gcc bug or whatever.

In any case, installing a VM of a system that causes problems is not
such a huge ordeal, and Mageia installs and runs fine inside VirtualBox,
which is gratis and open source and usable. For this KDE bug report -
https://bugs.kde.org/show_bug.cgi?id=224447#c103 - I set up and
installed an Archlinux VM, which was a frustrating experience, only to
see if I can reproduce that bug (which wasn't introduced by me, but
which I could not reproduce on my local system) and I also set up a
Debian 7.0.0 VM for debugging this perl problem now (which was more time
consuming than setting up a Mageia 3 VM).

Hi all,

I am now getting the same test failures after building a threaded perl
using
https://github.com/shlomif/build-perl-with-failure-on-i586/blob/master/build-perl-with-failure.bash
, and running
https://github.com/shlomif/build-perl-with-failure-on-i586/blob/master/run_only_failing_test.bash
on a most up-to-date http://manjaro.org/ i586 VM (= Manjaro Linux, an
Arch Linux derivative). Please let me know if you need any more
information. So it influences more than just Mageia Linux 3.

Threaded perl-5.18.0 fails the re/pat_rt_report_thr.t test script on
Mageia Linux 3 i586 (32-bit x86 - NOT x86-64). To reproduce, use Mageia Linux
The failure on Megeia essentially comes down to:

[***@localhost perl]$ ./perl -Ilib -Mthreads -le 'sub foo { $s = "\x{1ff}" . "f" x 32000; my $r = $s =~ /\x{1ff}f*/gc; print $r; print pos($s) } foo()'

1

Note that the pos() value is low even for smaller strings:

[***@localhost perl]$ ./perl -Ilib -Mthreads -le 'sub foo { $s = "\x{1ff}" . "f" x 32; my $r = $s =~ /\x{1ff}f*/gc; print $r; print pos($s) } my $t = threads->create(\&foo); $t->join'

A bit of "printf" debugging, and I believe it's a bug in perl, not in
Mageia's libraries.

S_regrepeat() sets max to I32_MAX when the supplied value is
REG_INFTY:

if (max == REG_INFTY)
max = I32_MAX;

so at this point max is half our address space.

If the character we're matching ('f' in this case) is invariant (it
is) and the regexp and string are the same type UTF-8-wise, we take
the simple branch.

In the simple branch, then:

if (utf8_target && scan + max < loceol) {
/* We didn't adjust <loceol> because is UTF-8, but ok to do so,
* since here, to match at all, 1 char == 1 byte */
loceol = scan + max;
}

Our test regexp is UTF-8, if scan were under 0x80000000 this code
would be sane, unfortunately, the string in my test cases we being
allocated at very high address, from debugging code I added:

Trying to match EXACT \x66 vs \x66 (@b690046a eol 36900469 regeol b690048a)

(scan = b690046a, loceol = 36900469, PL_regeol = b690048a)

so our C<< scan + max < loceol >> condition is true, and the pointer
addition overflows.

The scan loop:

while (scan < loceol && UCHARAT(scan) == c) {
scan++;
}

then terminates early since loceol starts out less than scan.

I suspect that Perl's malloc can be (ab)used so that it always allocates
"more core" by using mmap. But in turn I don't know if mmap() can be told
to allocate address above 2G (distinct from "allocate at this address).
And I agree, I'm not sure if it's worth it.

The change is essentially four variants of this:

- if (utf8_target && scan + max < loceol) {
+ if (utf8_target && loceol - scan > max) {

I think this is correct only if scan and loceol are guaranteed to be
pointers into the same string, and the difference guaranteed to fit in
I32 (the type of I<max>) without wrapping.

I think the former is intended to be the case, but the docs and comments
do not clearly indicate it, and I can't easily prove it. I've no idea
under what circumstances the latter is guaranteed.

I wonder whether it would make all this significantly clearer if
almost all these pointers were replaced with offsets. In particular,
it might make rather more obvious if we are trying to do stuff that
simply isn't going to work when a string can exceed 2GB.

I don't think the change makes anything worse, in the sense that I don't
think there's a universe in which the new code can go wrong but the old
code can't. But if there are any universes in which the new code can go
wrong, then in some of those universes I believe it may go wrong more,
or worse, than the old code. Hope that helps. :)

For the record, in this case I also think one commit would have been
a (small) improvement over four.

The difference isn't required to fit into I32 - C's promotion rules
will upgrade both sides of the comparison to the larger of ptrdiff_t
or I32, the type of the left and right sides of the comparison.

scan and loceol are pointers in the string being matched against -
scan is the current position being matched, loceol is initialized with
the end of the string and otherwise set to values within the string
(without the changes loceol could point outside the string.)

I think the former is intended to be the case, but the docs and comments
do not clearly indicate it, and I can't easily prove it. I've no idea
under what circumstances the latter is guaranteed.
It's clearer with davem's changes in blead where PL_regeol has become
reginfo->strend.

I wonder whether it would make all this significantly clearer if
almost all these pointers were replaced with offsets. In particular,
it might make rather more obvious if we are trying to do stuff that
simply isn't going to work when a string can exceed 2GB.
Neither version has a problem with strings larger than 2GB, but
neither will match more than 2**31-1 items.

I don't think the change makes anything worse, in the sense that I don't
think there's a universe in which the new code can go wrong but the old
code can't. But if there are any universes in which the new code can go
wrong, then in some of those universes I believe it may go wrong more,
or worse, than the old code. Hope that helps. :)
Please propose an example.

For the record, in this case I also think one commit would have been
a (small) improvement over four.
I mostly wanted to make the fixes match the tests added (for the two
cases where tests were added.)
