you must be doing something with internal redirects _someplace_. I'm
running CVS versions of both Apache and mod_perl and the below script
gives me exactly what we all expect (both using Apache::Registry and
modified as a standalone PerlHandler).
I'd try turning on mod_perl debug mode (assuming you built with a
debugging perl):
PerlSetEnv MOD_PERL_TRACE all
and see if you can see the redirect taking place.
I'm sure that if r->prev were _always_ defined lots of stuff would be
breaking for lots of people. after all, what's in r->prev if there is
no subrequest? the main request was somehow copied into r->prev
without anybody asking for it?
if you can't see an internal redirect anyplace and still think this is
a bug, then I'd suggest stripping down your httpd.conf to a bare
minimum and creating a test case that we can plug in and try in order
to isolate the issue and see what's going on.
