Bug report re httpd -S
Hi
When I run httpd -S against any configuration file containing a
VirtualHost directive within a Perl Section, libhttpd.ep receives
SIGSEGV and dumps core. (This happens whether I use full Perl syntax
or $PerlConfig.) The stack trace from the core file is :
(dbx) where

hmm, -S shouldn't produce that stack, show_compile_settings() is only
called with -V

maybe that's the problem, have you tried with a static mod_perl?

I dropped this in mod_perl-1.21_01-dev/t/conf/httpd.conf
and ran with no problem:
% ../apache-1.3/src/httpd -d `pwd`/t -f `pwd`/t/conf/httpd.conf -S
VirtualHost configuration:
172.16.125.46:8529 ln16p1166swk ((null):0)
