Hi,
Please try to add a
PerlModule Embperl
After the LoadModule embperl_module ....
Into your httpd.conf
Now I only ever get the second version (no content from .epl pages, and "/perl-status?Embperl" crashes.)

I am getting a consistent segfault in Embperl, that I'd like some help in diagnosing. I am using:
RHEL AS 4, kernel 2.6.11 with these things I compiled myself: apache 2.0.53 perl 5.8.6 mod_perl-2.0.0-RC4 Embperl 2.0rc2
The problem happens with earlier versions of everything, as well (even Emb 1.x). Here is the relevant section of httpd.conf:
AddType text/html .epl LoadModule embperl_module /usr/lib/perl5/site_perl/5.8.6/i686-linux/auto/Embperl/Embperl.so Embperl_UseEnv on SetEnv EMBPERL_DEBUG 0 SetEnv EMBPERL_APPNAME lottery SetEnv EMBPERL_SESSION_HANDLER_CLASS no PerlSetEnv EMBPERL_SESSION_HANDLER_CLASS no
<Files *.epl> PerlSetEnv EMBPERL_SESSION_HANDLER_CLASS no SetHandler perl-script PerlResponseHandler Embperl::Object Options ExecCGI </Files>
<Location /lottery> DirectoryIndex index.epl index.html index.shtml default.html blocked.html PerlSetEnv EMBPERL_OBJECT_BASE hello.epl PerlSetEnv EMBPERL_FILESMATCH "\.epl$" PerlResponseHandler Embperl::Object </Location>
The above config uses "hello.epl", which is just:
<HTML><HEAD></HEAD><BODY> [+ "Hello world!" +] </BODY></HTML>
If I do not include a "use Embperl" line in my startup script, then the first request for a ".epl" file works fine, but the second request for the *same page* will segfault. This is the output from a gdb run with "-X -DSSL":

This is similar to a problem encountered in this thread:
http://www2.ecos.de/~mailarc/embperl/2004-04/msg00110.html
the solution for which was to include "use Embperl" in the startup script. But if I do this, then:
- web pages which use Embperl (ending in .epl) return no content and no errorssegfaults:
