Hello I have a problem running mod_perl-2.0.0 (and the latest devel snapshot too):
Apache segfaults on startup as soon as I have the LoadModule directive in the httpd.conf. This also happens when running make test. I have compiled mod_perl with debugging enabled and found the problematic spot, however I have no idea on what exactly is wrong: (gdb output after segfault): [Mon May 23 17:10:32 2005] [info] 6 Apache2:: modules loaded [Mon May 23 17:10:32 2005] [info] 0 APR:: modules loaded [Mon May 23 17:10:32 2005] [info] base server + 27 vhosts ready to run tests Program received signal SIGSEGV, Segmentation fault.

So there seems to be a problem with reading configuration files/directories somehow.
