Hi, running FreBSD 7.2 amd64 I have a small perl script that queries LDAP attributes using Net::LDAP(S). I query a source and after that a destination. I decided to give threads a chance so I recompiled perl 5.8 to use threads. I also recompiled everything depending on perl (at least what pkg_info -R perl-5.8.9_3) reported. The thread itself runs fine using "my $srcThread = threads->create()", but as soon as I commit it using "$srcThread->join();" perl cores. It's only my $srcThread = threads->create($mySub, "param1, param2, ...) $srcThread->join(); nothing in between.

I'm no expert in coding (neither C nor Perl) but as far as I read by now Perl should *never* core. Thanks, Helmut
