Nah, the core file by itself is not exactly super usefull. You just

to figure out how to get a debugging build. Also, I've tried to

this on OS X/Apache 2.2.8 prefork/ Perl 5.10 without any luck.
Can you post the exact details on how you built each of these ?
For me, it goes something like:
perl> ./Configure -des \
-Doptimize=-g \
-Dprefix=$HOME/opt/perl.org/perl/5.10.0/debug
For me:
perl-5.10.0> sh Configure -des \
-Duseshrplib\
-Dprefix=/usr/local/perl-5.10.0.d \
-Doptimize='-g'
apache> CFLAGS="-g" ./configure \
--with-included-apr \
--with-mpm=prefork \
--enable-maintainer-mode \
--enable-modules=all \
--neable-mods-shared=max \
--prefix=$HOME/opt/apache.org/httpd/2.2.8/prefork-debug
For me:
httpd-2.2.8>export CPPFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"
export CFLAGS="-DAP_UNSAFE_ERROR_LOG_UNESCAPED -g"
./configure \
--prefix=/usr/local/apache2 \
--with-mpm=prefork \
--enable-dav \
--enable-dav-fs \
--enable-log-config \
--enable-authn-file \
--enable-authz-host \
--enable-authz-group \
--enable-authz-user \
--prefix=/usr/local/apache2.d \
--enable-mods-shared="rewrite info worker proxy deflate mod_auth
include ssl env mime-magic auth_digest expires dav dav_fs perl"
So I added the -g to CFLAGS. I didn't have that before. Instead I used
--enable-maintainer-mode as documented in
http://perl.apache.org/docs/2.0/devel/debug/c.html#Analyzing_Dumped_Core_Files
Is that out of date, perhaps?
mod_perl> perl Makefile.PL \
MP_APXS=$HOME/opt/apache.org/httpd/2.2.8/prefork-debug/bin/apxs
MP_MAINTAINER=1 \
MP_DEBUG=1
For me:
mod_perl-2.0.4>/usr/local/perl-5.10.0.d/bin/perl Makefile.PL \
MP_AP_PREFIX=/usr/local/apache2.d \
MP_MAINTAINER=1 \
MP_PROMPT_DEFAULT=1 \
The above URL doesn't have the MP_MAINTAINER=1 bit, but I followed
your lead. Should it have that?
Ah, bloody hell! Now I get this:

WTF? I could have sworn I built a debugging mod_perl before. Could it
be choking on Perl 5.10 here, too?
Thanks,
David
