Hi All,
I'm using modperl2 with PerlRun to invoke my cgi script. My server
configuration is as follows
Apache/2.2.6 (Unix) Axis2C/1.3.1 mod_perl/2.0.4 Perl/v5.10.0
script I invoke via mod_perl2 (say echo_service.pl) call to some other C
program. In that c program going to invoke a perl function. However when I
call perl function from C ,perl_parse method seems freeing some resources
that mod_perl2 using.
Here is the valgrind trace.

Any idea on fixing this segmentation fault would be a great help.
