To get a core dump when a warning is issued, set $SIG{__WARN__} to produce a core dump. For example:

use warnings;

my @x = qw(a b c);

$SIG{__WARN__} = sub { print "got a warning: $_[0]\n"; CORE::dump; };

for (0..3) {
    print "$x[$_]\n";
}

Remember to set your process limit to allow the core file to be produced (ulimit -c if you are using bash, see the man bash for details of ulimit).
