Thanks, but you have missed the core dump's backtrace.
I am sorry but I have never used core files before, so forgive me if I have done this all wrong.
No worries, this task is not trivial. Your trace is almost perfect. The only missing things are the arguments to the functions in the trace. In order to get the arguments you need to rebuild mp with MP_DEBUG=1 as explained here:
http://perl.apache.org/docs/2.0/user/help/help.html#Resolving_Segmentation_Faults
(gdb) backtrace #0 0x4051cf58 in modperl_wbucket_flush () from /usr/lib/apache2/modules/mod_perl.so #1 0x4066f5de in XS_Apache__SubRequest_run () from /usr/local/lib/perl/5.8.0/auto/Apache/SubRequest/SubRequest.so
Normally you should rebuild perl and apache with appropriate options as explained at the URL above to get the arguments for the perl and apache functions, but in this case the bug is most likely in mod_perl, so only rebuilding mod_perl with MP_DEBUG=1, getting a new segfault and a new trace will do.

I have not included the core file here because it was ~ 3Mb If you need it please let me know
That was a wise decision. A core file is not very useful for our purposes if taken away from the setup it was originated from. Not talking about the fact that posting large emails is not appreciated. If such a need rises, one needs to upload the file somewhere on the web and post the URL to that file instead.
