SOLVED: Segfault with Embperl, Apache::Session (piece of %@#!*)
Fickle, fickle machines.
The segfault problem with Embperl and Apache::Session can be fixed with about 3
keystrokes in emacs.
When I was getting the segfault error I had:
# BEGIN EMBPERL SESSION HANDLING
PerlSetEnv EMBPERL_SESSION_CLASSES "DBIStore SysVSemaphoreLocker"
PerlSetEnv EMBPERL_SESSION_ARGS "DataSource=dbi:mysql:sessions UserName=root"
PerlRequire startup.pl
PerlModule Apache::AuthenDBI
PerlModule HTML::Embperl
If you move the PerlRequire below PerlModule HTML::Embperl everything works. Of
course, it makes sense because startup.pl has the line for setting nsems for
Apache::Session::SysVSemaphoreLocker and Embperl loads that module for you so
startup.pl needs to load after Embperl.
The interesting thing is that with perl5.004 I was getting segfaults. After
building perl5.005 and rebuilding all the modules, apache and mod_perl I no
longer got segfaults but got Invalid argument errors from SysVSemaphoreLocker.
Either perl5.005 or the newer versions of Apache::Session or IPC::Semaphore are
a little bit more tolerant to misplaced parameters.
Gerald, if it's not on the wish list already, could you add a request for the
ability to set nsems in EMBPERL_SESSION_ARGS. Or maybe I should just get off my
butt and make a patch.

This works already. You can give any arguments to EMBPERL_SESSION_ARGS that
a Store or Locker module accepts. Embperl only pass them thru. e.g.
PerlSetEnv EMBPERL_SESSION_ARGS "DataSource=dbi:mysql:sessions UserName=root
NSems=16"
