'The handle is invalid' at rxd.pl line

The handle in question would have to be the thread handle itself; which suggests that it has some how become invalid between beong returned from threads->list(threads::joinable) and your calling join(). Which -- provided there are no other detach() than the one shown commented out -- should not be possible!

As a discovery measure, you could try calling the handle method pprint $join->_handle(); prior to doing the join and see what that yields?

The only other diagnostic measures I can think of, would entail adding some trace into the threads.xs module. If you're up for that, you could try adding:

printf( "thread handle:%x thread-id: %dx\n", thread->handle, GetThread
+Id( thread->handle ) );

just before the if(WaitForSingleObject()) call. It might add some info.

You should also add a call to GetLastError() and print out that and teh failing return code within the body of the if, prior to the PANIC.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
