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;开发者_高级运维

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

(program taken from Problem with perl signal INT)

The perl 5.10 version is:

$ perl5.10.0 -v

This is perl, v5.10.0 built for i686-linux-thread-multi
(with 3 registered patches, see perl -V for more detail)

You're going to need to provide some more details, such as what operating system/version you are using, whether you're using system perl, perlbrew, active perl, etc. Trying this against Perl 5.12.3 built from Perlbrew on Snow Leopard, I cannot reproduce the issue.

I would also follow the suggestion of asking on perlmonks.org, too.
