Okay, did this:

-Dprefix=/usr/local/perl-5.10.0.d \
-Doptimize='-g3 -O0 -DDEBUGGING'

in bash, you don't need to use the exports like that....

This merely adds -DAP_DEBUG which does not include -g, so yes, thats
out of date.
Okay, did this:
export CPPFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"
export CFLAGS="-DAP_UNSAFE_ERROR_LOG_UNESCAPED -g"

If you just want to see it compile, edit lib/Apache2/Build.pm and
remove
- -Werror stuff.
in todo/bugs_build I see that I wrote
==gcc 4.x and higher compiles break under -Werror
==[pgollucci volunteers]
that might be fixed because I did build it recently on FreeBSD with
4.2.x.....

Definitely a perl 5.10 bug in Darwin. Take it to p5p :)
You are not the first to post this.
Now I get this from svn head:

:-(
So I commented-out this line:
$Wall .= " -Werror" if $] >= 5.006002;
And all was well.
I then ran the code to get the core dump. Just a a reminder, here is
the httpd.conf:
LoadModule perl_module modules/mod_perl.so
ServerName localhost
ServerRoot /usr/local/apache2
PidFile logs/httpd.pid
Listen 80
User daemon
Group daemon
StartServers 2
ErrorLog logs/error_log
CustomLog logs/access_log combined
TypesConfig conf/mime.types
PerlModule mod_perl2
PerlPassEnv PERL5LIB
PerlModule MyConfig
And here is MyConfig.pm:
package MyConfig;
require Apache2::ServerUtil;
my $s = Apache2::ServerUtil->server;
$s->add_config([
'NameVirtualHost *:80',
'<VirtualHost *:80>',
' DocumentRoot /usr/local/apache2/htdocs',
'</VirtualHost>',
]);
1;
I ran it like so:
sudo env PERL5LIB=/Users/david/Desktop /usr/local/apache2-debug/bin/
httpd -f /Users/david/Desktop/httpd.conf
This did generate a core file, but its backtrace doesn't look
particuarly interesting:
