Cygwin Perl 5.8.7 - Thread signalling gives errors in standard distribution

Hi All,

I just experienced the following problem: When using the normal perl 
packaged with Cygwin (v5.8.7 built for cygwin-thread-multi-64int) and 
trying thread signalling with threads->kill(), I get an error.
For example the following script:

    use threads;
    sub thr_func
        $SIG{'KILL'} = sub { die("Thread killed\n"); };
        while (1) {}

    my $thr = threads->create('thr_func');

Errors out with:
Can't locate auto/threads/ in @INC (@INC contains: ...) at 
./ line 22
A thread exited while 2 threads were running.

After installing the newest threads module from CPAN (v1.57,, everything works fine. 
I believe, the cygwin distribution still uses an outdated threads 
module. Has anybody else experienced this problem?

Regards, Sebastian
