Mine are static, but I have the same module set, plus proxy and loggers

Very good! Only, I didn't find a reason in them why apache would SEGV (as
expected, since it seems not to be directly related to specific URLs).
The SEGV trace is a request "GET / HTTP/1.0" which can (probably) be tried
over and over again without a dump. *Somewhere* we're corrupting memory,
and much later does it cause apache to trip over it.
