Steve, Randy, please try the current cvs (just cvs up + make, no need to rebuild from scratch). I have finally been able to solve the segfault with the short config Steve presented. I hope that it solves the problem for you as well. If it does, please try again with the vhost patch that was failing before.
I moved quite a few things in mod_perl.c, but the only real change was adding:
+#ifdef USE_ITHREADS + /* after other parent perls were started in vhosts, make sure that + * the context is set to the base_perl */ + PERL_SET_CONTEXT(base_perl); +#endif
after setting up vhosts, without which, PerlLoadModule in the main server was segfaulting for me.
The good news: The short configuration file that I posted now works for me too (both the -t test and actually starting up the server).
The bad news: The vhost tests still fail as before :(
Here's a backtrace of the crash:

I'll try to cut down the conf file to the minimum that still crashes, and post a full trace then.
