https://bugzilla.redhat.com/show_bug.cgi?id=967719 Bug ID: 967719 Summary: Segfault in Perl_gv_fetchpvn_flags when trying to initialize back_perl openldap backend Product: Fedora Version: 19 Component: perl Severity: unspecified Priority: unspecified Assignee: mmaslano@xxxxxxxxxx Reporter: jsynacek@xxxxxxxxxx QA Contact: extras-qa@xxxxxxxxxxxxxxxxx CC: cweyl@xxxxxxxxxxxxxxx, iarnell@xxxxxxxxx, jplesnik@xxxxxxxxxx, kasal@xxxxxx, lkundrak@xxxxx, mmaslano@xxxxxxxxxx, perl-devel@xxxxxxxxxxxxxxxxxxxxxxx, ppisar@xxxxxxxxxx, psabata@xxxxxxxxxx, rc040203@xxxxxxxxxx, tcallawa@xxxxxxxxxx Created attachment 753756 --> https://bugzilla.redhat.com/attachment.cgi?id=753756&action=edit Reproducer pack Description of problem: When trying to initialize back_perl, a segfault occurs deep in perl itself. Version-Release number of selected component (if applicable): perl-5.16.3-264.fc19.x86_64 openldap-2.4.35-4.fc19.x86_64 How reproducible: Almost always. Steps to Reproduce: 1. Install fresh F19 2. If you try the reproducer here, all goes well 3. yum install perl-A* (I have no idea why I needed to do this to get it to segfault) 4. Try reproducer 5. Observe the segfault 6. From now on, reproducer works *without* producing any segfaults. I had to reboot the machine to be able to reproduce the issue again. Note on how to use the reproducer: 1. Unpack 2. Run go.sh (warning: it will wipe your /var/lib/ldap/* and your /etc/openldap/*, so don't run if you use openldap in production) This will run slapd in debug mode, so you will need another console to run the rest. 3. Run try.sh 4. If you want to repeat, go to 2. You can modify go.sh to run slapd through a debugger. However, you will probably need to set LD_PRELOAD=/usr/lib64/perl5/CORE/libperl.so to be able to run try.sh. Actual results: Perl segfaults. Expected results: The back_perl gets initialized without any problems. Additional info: This also happens on my production F18, but it happens always. It looks like it might have something to do with Bug 960048. -- You are receiving this mail because: You are on the CC list for the bug.
