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.

In order to isolate the problem further I changed line 118 of modperl_pcw.c from
if (dir_cb) {
to
if (dir_cb && 0) {
and mod-perl2 started working! So there seems to be a problem with
reading configuration files/directories somehow.
Thank you for your help and regards
