apache/mod_perl sigsegvs in parse_log_string

[Ask Bjoern Hansen <as...@netcetera.dk>]

I can't figure this one out. The httpd coredumps when it reads the
config file. I have tried everything like cleaning the sourcetree and
recompiling. It looks like apache without mod_perl works okey, but I'm
cc'ing new-httpd anyway since the backtrace ends in an apache module.

Latest modperl+apache (from cvs), pretty fresh redhat 5.2 system. I
compiled with this makepl_args.mod_perl file:

EVERYTHING=1
DO_HTTPD=1
PERL_TRACE=1
PERL_DEBUG=1
APACHE_PREFIX=~value/apache
APACHE_SRC=/usr/src/apache/apache-1.3
USE_APACI=1
ADD_MODULE=rewrite

apache coredumps in 'make start_httpd', like this:

[ask@embla modperl]$ gdb ../apache-1.3/src/httpd
 ... gdb blah blah ...
(gdb) run -f  /usr/src/apache/modperl/t/conf/httpd.conf -X -d /usr/src/apache/modperl/t/conf
