-8<-- Start Bug Report 8<--
1. Problem Description:
Apache2 segfaults when a virtual host is configured with
PerlOptions -Enable (using the libapache2-mod-perl2 package on a
stock Ubuntu 7.04 installation).
A test case using bug-reporting-skeleton-mp2.tar.gz is available at
http://www.ece.ubc.ca/~derekp/webdevel/mp2-perloptions-enable-bug.tar.gz
A patch to fix the segfault is included below. While it does fix the
segfault, it is not thoroughly tested.
