Hi!
1. Problem Description:
My apache child crash with a segfault when I call a page which generates a graph
using the perl module GD::Graph.
My system specs are:
Fedora Core 1
httpd-2.0.47 (from fedora, also tried with self-compiled 2.0.48)
mod_perl-1.99_11 (the final version, self-compiled)
embperl-2.0b10 (current cvs snapshot, self-compiled)
perl-5.8.1 (from fedora, also tried with self-compiled 5.8.2)
gd-2.0.15 (from fedora, also tried with self-compiled 2.0.15)
freetype-2.1.4 (from fedora, also tried with self-compiled 2.1.5)
All perl modules are the newest version from CPAN.
The reported versions are my current state:
httpd from fedora, everything else self-compiled.

*** mod_perl version 1.9911

3. This is the core dump trace: (if you get a core dump):
I tried but I can't catch any (I don't know and didn't manage to find out which
directory has to be writeable for the apache2 process under Embperl).
