Hi!
Sorry, I did not check if this is known problem.
I recently forgot to follow through with a name change (equivalent to
renaming Some::SimpleModule to Some::Simple::Module). I moved the
file, but forgot to change the package name.
Here is a much smaller version of my module that shows the problem:
package Some::SimpleModule;
use Apache::Constants qw(:http);
sub handler {
return DECLINED;
}
1;
Add this to a standard http.conf.default:
<Location /test>
SetHandler perl-script
PerlHandler Some::Simple::Module
</Location>
Then try accessing http://localhost/test.
In the error log with full trace on:
running 1 server configured stacked handlers for /test...

perl_setup_env...26 keys

(Getting the coredump in Solaris requires some version dependent
fiddling. This is Solaris 8, where I just use coreadm.)
This is the stack trace from the core:

I believe this crash happens because sv_2cv returns a NULL pointer.
Then, CvFLAGS(cv) is used to access the flags field of a nonexistent
structure.
Sorry, I have no idea what to patch here. Holding for the Gurus ... ;-)
Probably this should be caught in perl_call_handler().
