It appears as though the dynamic loader is crashing when I try to load a
custom apache module.  I recompiled apache with debugging on and here's the
trace:

(gdb) r -X

The module is also linked staticly against libmysqlclient, and dynamicly
against libpthread, libz & libm.  Unfortunately, the module is proprietary
so I can't really give any more details that this.  The same module worked
fine on RH6.0 using apache 1.3.9 & I just tested that 1.3.11 & 1.3.12 work
under RH6.0 as well.
