OOOHH Seriously, tho, do you think you could come up with a short list of definitions for those macros? I was pretty excited to see them, once, except that I couldn't make them work. Even a comment w/ a usage: AvFILL() just to see what to feed the macro from gdb space? Not like you have anything ELSE to do... (JUST KIDDING I can tell you've been writing email *all day* by the posts that keep trickling into the list). L8r, Rob

You could try to use Carp with $SIG{__(DIE|WARN)__}. But mainly read the
perlsec manpage. Also see:
http://perl.apache.org/guide/perl.html#Exception_Handling_for_mod_perl
regarding the catching of exceptions.

Tracking down taint problems
I recently got this error: Insecure dependency in eval while running with -T switch. Callback called exit. Now, yes that tells me that something is wrong. What it doesn't tell me is where the problem is except for the fact that its somewhere in the current module that's being run. Is there a way that I could get mod_perl to fess up where the problem is? Jamie Krasnoo [EMAIL PROTECTED]
