Subject bug report: wrong line number if using built-in functions
Date Thu, 19 Jun 2008 17:05:57 GMT

-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:

Line numbers will be wrong if a bulit-in function's first parameter is not
in the same line.

Minimized example:

01: #!/usr/local/bin/perl
02: use strict;
03: use warnings;
04:
05: abs
06:
07:    5;
08:
09: die __LINE__;
10:
11: __END__

Expected line is 9. Result is 11.

-> Warnings and dies give wrong line numbers. Finding errors is difficult 
so.


2. Used Components and their Configuration:

*** mod_perl version 2.000002

*** using
