-------------8<---------- Start Bug Report ------------8<---------- 1. Problem Description:
On a plain boring box running debian stable, the simplest build of apache 2.0.51 with a static linked mod_perl 1.99.16 segfaults immediately on start. I've been running round in circles on this all evening, any assistance would be hugely appreciated. :(
The entire install was built by downloading & expanding apache & mod_perl, and then running:
$ perl Makefile.PL \
MP_AP_PREFIX=../httpd-2.0.51/ \
MP_AP_BUILD=1 \
MP_DEBUG=1 \
MP_INST_APACHE2=1 \
MP_AP_CONFIGURE="--enable-maintainer-mode --prefix=/usr/local/apache2 --localstatedir=/var/run/apache2 --with-mpm=prefork"
$ make
# make install
$ make test
in the mod_perl source tree.
2. Used Components and their Configuration:
*** mod_perl version 1.9916
