Been looking around but cant find any mention of it so asking here:
Is there a known issue with the latest 1.5.25 + perl 5.10 threads,
as doing anything with threads here causes an instant crash.

[test]
#!/bin/perl -w

use warnings;
use strict;
use threads;

print STDERR "Testing threads...\n";
my $thrd = threads->create( \&dothread );
$thrd->join();
print STDERR "Testing done\n";

sub dothread { print STDERR "I'm a thread!\n" }
[/test]
