generated with the help of perlbug 1.39 running under perl 5.17.3.
-----------------------------------------------------------------
[Please describe your issue here]
Following code causes SIGSEGV. Neither changing package or blessed
object doesn't change this bug or make it disappear.
use strict;
use warnings;
use overload '*' => sub {
my ($a, $b) = @_;
$a * $b;
};
# Causes infinite recursion on overload '*' and SIGSEGV.
