Annoying Segfaults and Bus Errors in 1.3.4
Howdy,
We just recently upgraded to 1.3.4 and are suddenly getting random
segfaults and bus errors.
Server: Stronghold/2.4.2 Apache/1.3.6 C2NetEU/2412 (Unix) mod_perl/1.25
perl5 (5.0 patchlevel 5 subversion 3)
Here is the backtrace of one of the core files, all of the ones we've
collected look similar:

I'm already contemplating an upgrade to Stronghold 3 and mod_perl 1.26
but would rather just figure out what is going on here.
Thanks for any help.

Hi,
sorry for the later answer, but this week is a really busy one for me...

Seems that the Apache request record is corrupted. The only reason I can
imagine at the moment is, that the new Embperl version was compiled
differently than the old one, e.g. different compiler or compiler settings.
For example with one of both is compiled for LARGE_FILES and one ins't the
request_rec structure changes and doesn't fit together.
I would suggest to recompile Apache + mod_perl + Embperl to make sure they
are all compiled with the same settings.
