Re: Segfault with Embperl, Apache::Session
The binaries on both boxes are the same. They get rdist'd out from one machine every night. I'm going to rebuild the latest versions of everything on the 2.7 machine tomorrow and see if that makes a difference.

RE: Segfault with Embperl, Apache::Session
this copy-n-paste from ~/Mail/.sent-mail-dec-1999 might help:
---
a few things could shed some more light:
build a libperld.a and compile with PERL_DEBUG=1 (see SUPPORT doc)
and/or, in gdb:
(gdb) source mod_perl-1.21/.gdbinit
(gdb) curinfo
should tell you the line/filename of the offending Perl code
add this to the .gdbinit (which is in the modperl cvs tree):
define longmess
set $sv = perl_eval_pv("Carp::longmess()", 1)
printf "%s\n", ((XPV*) ($sv)->sv_any )->xpv_pv
end
(gdb) longmess
should produce a Perl stacktrace

I would first try to recompile all modules (maybe Perl itself also), to make sure things fit together Gerald
