Ok, it's a bit clearer now:

And as far as I can tell, I'm running the prefork model, although gdb
does claim a thread gets forked off ?? (but from what I can tell from
the configuration-line in gentoo's ebuild and the output of ps, it
should be the prefork model)

Change your CFLAGS and CXXFLAGS to
CFLAGS='g3 -pipe' \
CXXFLAGS='-g3 -pipe' \
Are you using apache2 with fork() or thread model?

I'm sorry, when compiling with debug-symbols (--enable-debug) it
doesn't seem to happen...
Perhaps you can use this extra bit of information:
gcc = 3.3.2
glibc = 2.3.2
postgresql = 7.4.1
apache = 2.0.48
Even weirder, when I start apache2 -X, its opening two processes. The
manager (I suppose) and one handler (I suppose). The manager process
dies, the handler seems to survive (at least, the one with the higher
pid and which is displayed in the ps xaufww output as the lower one).
When I attach gdb to that process, it doesn't really do anything, but
if I attach gdb to the top process, it tells me there is a segfault and
I can get the above stacktrace again.
If you have any clues in how to build a proper debuggable php, please
let me know. My config.nice contains:
CFLAGS='-march=athlon-tbird -O3 -pipe' \
CXXFLAGS='-march=athlon-tbird -O3 -pipe' \
CC='gcc' \
CXX='g++' \
'./configure' \
'--with-apxs2=/usr/sbin/apxs2' \
'--with-zlib' \
'--with-mysql' \
'--with-pgsql'
I'll check whether it works correctly without the parameters, but they
shouldn't make any difference.

Could you please compile PHP with debug symbols and try
again. That would make the backtrace much more informative.
