I built the module from that source and it works for me. It doesn't crash. % curl -sI 'http://mbopensuse.suse.de/zrkadlo/repositories/Apache/openSUSE_11.0/Apache.repo?country=us' HTTP/1.1 302 Found Date: Fri, 23 Jan 2009 11:10:15 GMT Server: Apache/2.2.11 (Linux/SUSE) mod_zrkadlo/2.2 Location: http://localhost/abcdef Content-Type: text/html; charset=iso-8859-1 > > Can you reproduce it easily, i.e. with starting the server > > and issueing a single request? > > Yes, exactly.

I suggest you compile with debug symbols and run it under gdb. apxs2 -c -Wc,"-Wall -g" mod_hs.c # (make sure to load .libs/mod_hs.so) # start it under gdb like the following. It'll start only a single # process that doesn't fork, which makes it easier to debug the crash gdb --args /usr/sbin/httpd2-prefork -f /etc/apache2/httpd.conf -DONE_PROCESS -DNO_DETACH # type 'r' in gdb to run it # trigger the crash # look at back trace with 'bt' and 'l', observing the local variables I hope you get a good trace, which helps you further.
