Evening all, In perlthrtut.pod, at line ~850 there is an example called "prime-pthread". This has been broken at some point by a cleanup. I think all it needs to patch it is: - 16 threads->create(\&check_num, $stream, 2); + 16 my $kid = threads->create(\&check_num, $stream, 2); However, with this change it now works for the first 600 or so primes no problem, but then begins to issue "Scalar leaked: 1" warnings while continuing to print the correct prime numbers! By adding a C<die unless defined $kid> after the thread creation results in it stopping with "Thread 117 terminated abnormally: Died". So it's hitting a limit on the number of threads possible. (fwiw - this is on Win32). I'll leave it to someone with more thread-foo to untangle this :-) Cheers, alex.Thread Next
