Matthew, please try the current cvs, Philippe has been working hard on improving the static build since _16 was released.

Okay, my previous build using latest mod_perl cvs was slightly screwy due to not cleaning the build tree sufficiently & not realising that you now specify MP_USE_STATIC=1 to build a statically linked httpd. Armed with this knowledge, i'm happy to say that it doesn't crash under debian unstable - but under stable, the same problem presents itself. :(
(under debian unstable, I had to export -I/usr/lib/perl/5.8/CORE/ in CPPFLAGS for it to find the right perl headers when compiling)
-------------8<---------- Start Bug Report ------------8<---------- 1. Problem Description:
mod_perl 2.0 CVS head + apache 2.0.51 segfault at startup under debian stable. I also had to butcher ./src/modules/perl/modperl_exports.c to remove non-existent symbol references to get it to compile.
