Apache segmentation faults with RT 3.8.2

Hello everyone,

I get blank pages where I have to clear the cookie or restart my browser
to access RT again when using RT (Bulk Update RT, clicking browser back
button). These blank pages are logged as a segmentation fault (11) in
apache’s error log. I’ve searched the archives and I came up with a
reference to a buggy version of DBD::mysql which seems to describe the
exact problem:

http://www.gossamer-threads.com/lists/rt/users/80746

I did have a newer DBD::mysql (4.008), which I (think) I removed from
the system, and installed 4.004:

root@rt:~# locate mysql.pm | xargs grep “$VERSION =”
/usr/lib/perl5/site_perl/5.10.0/i486-linux-thread-multi/DBD/mysql.pm:$VERSION
= ‘4.004’;
/usr/lib/perl5/site_perl/5.10.0/i486-linux-thread-multi/Bundle/DBD/mysql.pm:$VERSION
= ‘4.004’;
/usr/lib/perl5/site_perl/5.10.0/DBIx/DBSchema/DBD/mysql.pm:$VERSION =
‘0.06’;

However, after downgrading/restarting apache I still get the blank
pages/segfault.

Some more info about the system in question:
Kernel: 2.6.27.7-smp
Distro: Slackware 12.2.0
Apache: Server version: Apache/2.2.10 (Unix), Server built: Oct 22
2008 17:54:27
Mod Perl: 2.0.4

Can anyone shed some light on this?

Thanks,
Richard

You would better use the latest (4.010), works fine here.

Hi Emmanuel,

Just tried 4.010 via cpan, restarted apache, same error.

Any ideas on getting some more debugging information on what’s causing
the segfault?
