The major differences:
I'm testing 64bit debian on the trunk of all projects (httpd, apr, mp2)
against a fresh perl-5.8.x snapshot, and I enabled every debugging option
I could think of (--enable-pool-debug, CFLAGS="-g3 -gdwarf-2 -O2",
CPPFLAGS="-DAPR_BUCKET_DEBUG"; MP_DEBUG=1; MP_MAINTAINER=1) when
compiling them.

I don't have gtop enabled.

Pretty much the same as mine, but with -lapr-1 and -laprutil-1. This
is a factor, because the segfaults are coming from libapr:
