Here is a bit of code with an error $var has not been defined
#! /usr/bin/perl
use strict ;
use warnings ;
$var = 42 ;
Run the above code with the debugger:
perl -d test.pl
Loading DB routines from perl5db.pl version 1.3
Editor support available.
Enter h or `h h' for help, or `man perldebug' for more help.
BEGIN not safe after errors--compilation aborted
at /usr/share/perl/5.10/Carp/Heavy.pm line 5.
Compilation failed in require at /usr/share/perl/5.10/Carp.pm line 33.
Debugged program terminated. Use q to quit or R to restart,
use o inhibit_exit to avoid stopping after program termination,
h q, h R or h o to get additional info.
Running perl test.pl (without the debugger) gives
Global symbol "$var" requires explicit package name at /dev/shm/test.pl
line 6.
Execution of /dev/shm/test.pl aborted due to compilation errors.
The following code produces the correct error with the debugger.
#! /usr/bin/perl
use strict ;
use warnings ;
use Carp::Heavy ;
$var = 42 ;
Why can't the debugger get it right?
