Description Giovanni Bechis 2018-07-03 08:45:05 UTC
Description of problem:
On upcoming 3.4.2 SpamAssassin idn_dots.t regression test fails only on RH systems.
Rebuilding an updated perl from src is a workaround.

How reproducible:
The problem appears on Rhel6, Rhel7 and the corresponding CentOS releases.

Steps to Reproduce:
svn checkout https://svn.apache.org/repos/asf/spamassassin/branches/3.4
cd 3.4
perl Makefile.PL
make
prove -v t/idn_dots.t
Actual results:
Regression test fails

Expected results:
Regression test passes

Additional info:
The regression test pass on:
Ubuntu Trusty, Perl 5.18.2-2ubuntu1.6
Ubuntu Xenial, Perl 5.22.1-9ubuntu0.5
MacOS X 10.6.8, Perl 5.26.2 (MacPorts build)
MacOS X 10.6.8, Perl v5.10.0 (Apple build)
MacOS X 10.11.6, Perl 5.26.2 (MacPorts build)
CentOS 7.5.1804, Perl 5.18.4 (Perl.org source, default build config)
CentOS 7.5.1804, Perl 5.28.0 (Perl.org source, default build config)
Fedora Core 27, Perl 5.26.2-406.fc27

Comment 3 Petr Pisar 2018-07-03 09:01:55 UTC
Could you please extract the failing code and paste/attach it here so that the issue can be reproduced without the SpamAssasin code base? My first impression is that it's an bug fixed in a Perl version later then 5.16.3 that you did not hit on MacOS X because RHEL builds packages with hardening compiler flags that can make some bugs visible.

If you need a help with minimizing the test, please contact Red Hat support.

Comment 5 Giovanni Bechis 2018-07-03 09:09:17 UTC
The regression test is working on "MacOS X 10.6.8, Perl v5.10.0 (Apple build)",
Anyway I will try to find a way to reproduce the problem using less code.

Comment 6 Giovanni Bechis 2018-07-03 09:25:29 UTC
I will also try a src-rpm build without hardening compiler flags to catch the error, thanks for the suggestion.

Comment 7 Giovanni Bechis 2018-07-11 18:20:13 UTC
Test passes on CentOS 7.5 with perl 5.16 built from src.rpm (with all RH patches) but with -D_FORTIFY_SOURCE=0.
This is definitely a Perl bug that has been fixed in later Perl versions.
