This looks like the main server (localhost:8529). I also tried it with
my default httpd.conf with all vhosts removed and it segfaults too,
and the gdb output looks the same...

I don't know. One thing I remember now seeing during one of the first
mod_perl build was a warning that apxs -q PREFIX doesn't return a
valid value. I fixed it then by setting it to / in the apxs script.
Maybe I managed to screw up apaches build, setting prefix to NULL?

And indeed I found that the custom layout for apache has prefix set to
NULL there. So I have rebuilded everything (apache, mod_perl) with
prefix set to / in the layout and the warnings are gone now.
Unfortunately this didn't help at all for the segfaulting :(

Hope that helps and kind regards
