Code is supposed to test, if the required auth type matches (set with AuthType
directive) with the auth type ("auth_xxx") that module handles. Now
ap_auth_type(r) seems to return pointer to memory location, that causes
segmentation fault when accessed (for example in sprintf("Auth type: %s",
ap_auth_type(r)).

I compiled module with following command:
/usr/sbin/apxs -Wcg -lmcrypt -c mod_auth_tek.c
After that I produced backtrace with following commands (did it couple of times
because of the apr_match_glob at the bottom):
gdb /usr/sbin/httpd -c /tmp/core.12451
(gdb) bt
I don't call apr_match_glob() directly, but assumed that ap_auth_type(r) call
caused the execution of the glob function.

Thanks for the hint. I'll try it next, if nothing else turns up.
