Hi, We are hitting a strange issue within our stack and `$threads::shared::threads_shared ` (see the attachment) variable somehow gets defined and causing the next function call to be triggered, which in turn dies on non-threaded perl. We are not sure what is causing this to happen but perhaps it is better to check something like below in there: use Config; if ($Config{usethreads} && threads::shared::_id($seed)) { or even if ($Config{usethreads} && $threads::shared::threads_shared && threads::shared::_id($seed)) {

Thank you for this problem report. I have taken your suggestion to use Config{useithreads} in conjunction with $threads::shared::threads_shared to handle the case where threads::shared is loaded on a non-threaded Perl instance. The fix has been distributed to CPAN as version 6.23. As I don't have a non-threaded Perl instance, I have not actually tested this fix, but I have reasonable confidence in my implementation. However, as I'm only human, please let me know if you have any further issues with this.
