Subject:    [mp2] segfault at startup under perl 5.8.1 and mod_perl-1.99_10-dev
From:       Matthew Darwin <matthew () mdarwin ! ca>

When I start httpd without the
    LoadModule perl_module modules/mod_perl.so
All is good.  When I add the line above, and start "httpd -X"
apache crashes before I even request the first page.

Has anyone else seen this problem?
