Hi Andrej,
Thanks for reporting this bug. I can reproduce it. And it is a quite
funny bug. The problem is actually the C optimizer is more powerful
nowadays.
So this bug is because a static variable modified by 2 threads.
One thread is using busy wait on that variable. And makes the optimizer
thinks that wait loop to be always true.
The fix is to mark that static variable volatile to not let the
optimizer optimize it.
I'll fix this bug soon.
Many Thanks,
Paul
