Description Stephan Kulow 2008-02-28 09:32:19 UTC

The user module crashes the installation. The log says:
[Y2Perl] Shutting down embedded Perl Interpreter 
.. Caught Segmentation Fault

The backtrace is full of (recursive) libperl symbols. I guess perl doesn't like to be shutdown.

Thanks, my X server crashed on distupgrade, so I didn't have it available.

Comment 4 Martin Vidner 2008-02-29 16:17:33 UTC

I can reproduce the bug. Y2DEBUG shows that ag_crack gets called and then suddenly zypp is cleaning up and then Perl dies, leaving some assertion failures (on tty10 because yast runs in gdb). strange.

Comment 5 Stephan Kulow 2008-03-03 16:40:24 UTC

not sure I would trust my instsys debugging abilities, but just commenting out the destructor didn't seem to help.

Comment 7 Martin Vidner 2008-03-04 10:11:17 UTC

I suspect that Perl got an error and wants to shut down. A complication is that the many assertion failures may hide earlier Perl error messages.

Let's try redirecting the output to a file.
BTW Arvin do you know already about GDB starting unconditionally?

To reproduce, boot from http://download.opensuse.org/distribution/SL-OSS-factory/inst-source/boot/boot.iso

Comment 8 Martin Vidner 2008-03-04 13:18:57 UTC

I redirected the output to a file:
(gdb) r installation '("initial")' qt --noborder --auto-fonts --fullscreen > /root/out 2>&1

and found:
/usr/lib/cracklib_dict.pwd: No such file or directory
PWOpen: No such file or directory
Attempt to free temp prematurely: SV 0x1237489 [...perl assertion failures...]

That file is a dangling symlink to ../share/cracklib/pw_dict.pwd

Maybe some code could be made more robust. In perl:
  eval {
   crackme();
  }
  if $@ y2error...

Steffen, please include also the linked files from cracklib.rpm (fate
