(this question was originally posted on stackoverflow: http://stackoverflow.com/questions/5560866/perl-5-10-0-signal-handler-issue)

Interrupting the program below with Ctrl + C causes a "Segmentation fault" with perl 5.10.0. It works correctly with perl 5.8.8. Any idea why?

#!/usr/bin/perl

# just changing the shebang line to use perl 5.10.0 causes
# it to seg fault when interrupted with Ctrl + C

use strict;
use warnings;

$SIG{INT}=\&clean;

sub clean {
    print 'caught';
}
sleep 10;
