Package: speedy-cgi-perl
Version: 2.22-10
Severity: normal
Hi
After upgrading my server to Lenny, I'm seeing regular segfaults of
speedy_backend in my syslog:
Jul 22 10:26:19 chandra kernel: speedy_backend[17306]: segfault at 206024a ip
b7e91585 sp bfb4e6f0 error 4 in libperl.so.5.10.0[b7de0000+149000]
I've compiled a version of libperl5.10 with debug symbols and got
the backtrace bellow.
Not sure if this is a problem with speedy or Perl itself. The CGI script that
is crashing has been in use on Etch for a long time without problems and
segfaults don't seem to happen if I run the script under regular Perl.
Thanks
