core dump when merging directory configs
Ok.
I narrowed this down abit.
current CVS head
with a config with a section in my httpd.conf like:
<Location /test/>
</Location>
(it can have stuff inside of the location directive)
If I do a GET /test/index.html it works
if I do a GET /test/ it core dumps
any ideas?

Simpler example...
<Location /icons/>
</Location>
Request /icons/
I'm debugging now.

Re: core dump when merging directory configs
Posted by "William A. Rowe, Jr." <wr...@rowe-clan.net>.
The problem is this ...
sub_req (and perhaps redirect - I'm checking) don't set up the server/vhost
per_dir_config so ap_location_walk starts with a NULL r->per_dir_config pointer.
Since there _is_ a merge, and LHS is NULL, the request dies in the core default
(fallback) dir_merge.
I need to contemplate this for a bit, likely to patch it in about an hour.

I was just looking at exactly the same thing. It's unrelated to the
INTERNALLY GENERATED FOONESS thing. I'll keep looking...
