The new Obj vs. Obj->new doesn't require any support from the module
itself, but I tried it just to be sure, and still get the same
segfault.  Also, I do compile constants in the startup.pl script, and
when I remove the call to Apache2::Request in my sample handler, the
segfault goes away.

For perl, the non-path/compiler flag defines passed to Configure are:

-Duselargefiles
-Duseshrplib
-Dusesitecustomize
-Dusethreads

(Note: when I comment out the call to Apache2::Request in my example,
mod_perl happilly handles the request, so I think the perl/mod_perl
path is working fine.  The stack trace shows the segfault in
mod_apreq2.so)

mod_perl:

    MP_PROMPT_DEFAULT=3D1 \
    MP_DEBUG=3D1
