perlwarn break our CGIs

[JY - June Young <JY...@dymaxion.ca>]

 
Hi, all,

We are at a stage of converting CGI to run under mod_perl.

In order to help debugging our CGI code under mod_perl, we turned
PerlWarn On.

Unfortunately, after turning on PerlWarn, our CGIs that already run well
under mod_perl get broken with the message 

"page cannot be displayed" on browser. The error.log does not show the
corresponding error for the request, but list tons of warnings such as
"Use of uninitialized value in split at /perl_root/lib/Cwd.pm line 103
during global destruction".

Did anyone encounter the similar symptom?

I thought global destruction only happens when the server is shutdown or
a child server dies, but these messages came out upon the very first
request since the server restarts, and makes no sense too me. 

After I turn off PerlWarn, our CGIs that were broken start to work
again. Since the messages in error.log are only warning message, how
come the page is broken. Does PerlWarn outputs anything to places other
than error.log?

Welcome any help.
