Hi Anthony,
I don't see this code malfunctioning with my 4.7.2 build on Win64 (Windows
7 Ultimate x64 SP1).
I also tried the original example with two threads you posted earlier, and
that does seem to hang, although I can't pinpoint what's going on.
Attaching the VS debugger, all threads are have NtWaitForSingleObject at
the top of their call stack. I can't compile the code with MSVC and I don't
know if this would even help to find the underlying issue.
