this would appear on the page and/or in apache's log.
Again, testing r against NULL won't do what you want, I've experienced that r
stayed normal, while r->request_config simply changed from a normal pointer
address (like 0x8b5f1234) to 0x1000 (dec 65536, seems to be a error code, or a
flag) between mod_midgard and PHP_MINIT... but as I said before, once apache
was compiled with debug symbols, all worked fine.
If this can help someone, the procedure to find where it changed was to
execute httpd -X in gdb, then to put a breakpoint on line 1340 of mod_midgard.c:
ap_set_module_config(r->request_config, &midgard_module, (void *) rcfg);
then put a watch on the address of r->request_config
(gdb) watch (void *)&(r->request_config)
and continue the execution, but of course it stopped in the middle of httpd
which it didn't have the sources...
