HI Perrin,


I'm using Apache::RegistryFilter:

PerlHandler Apache::RegistryFilter Apache::Dynagzip

See the attached httpd.conf for full context etc.

This causes the same problem as:

$r = Apache->request();


Attached is my httpd.conf and a script test.cgi which reproduces the
problem I'm having. I'm using Apache/1.3.33 with mod_perl statically
linked.
