Bug#557771: *** stack smashing detected ***: /usr/bin/perl terminated

[Thomas Schwinge]

Package: perl
Version: 5.10.1-8
Severity: important

Hello!

I have a case where perl reproducibly crashed like this:

    [...]
    scanning tag/open_issue_viengoos.mdwn
    scanning tag/open_issue_xen.mdwn
    building render_locally
    building colophon.mdwn
    *** stack smashing detected ***: /usr/bin/perl terminated

This is when using ikiwiki, <http://packages.debian.org/ikiwiki>, for
rendering a set of web pages.

I have this sitting in GDB at the moment, but without debugging symbols
the backtrace is probably not to helpful for you:

    (gdb) bt
    #0  abort () at abort.c:55
    #1  0x0112c71c in __libc_message (do_abort=2, fmt=0x1214956 "*** %s ***: %s terminated\n") at ../sysdeps/posix/libc_fatal.c:138
    #2  0x011dc7db in __fortify_fail (msg=0x121493e "stack smashing detected") at fortify_fail.c:32
    #3  0x011dc790 in __stack_chk_fail () at stack_chk_fail.c:29

    #6  0x080a5d15 in Perl_yyparse ()
    #7  0x0811e93b in ?? ()

    #10 0x080770ee in perl_run ()
    #11 0x0806093d in main ()

How do you suggest to proceed with debugging this?
