[Petal] Petal and mod_perl

Wed, 31 Jul 2002 14:52:09 -0400

Ok, I've made some progress into debugging my seg faults under mod_perl. I'm 
using XML::Parser v2.31 which I reinstalled and retested with no errors. I followed 
the instructions in the guide to run Apache with Interactive mod_perl Debugging 
(see http://perl.apache.org/docs/1.0/guide/debug.html for details).

Here is the output I received:

21:             env => \%ENV,
22:             date => scalar localtime
23:     );

Line 184 in XML::Parser is an eval statement (the root of all evils!!). I haven't done 
any further investigation yet but wanted to pass this on to the list to see if anyone 
has any feedback.

Thanks,
