[New-bugs-announce] [issue33955] Implement PyOS_CheckStack on macOS using pthread_get_stack*_np

[Ronald Oussoren]

New submission from Ronald Oussoren <ronaldoussoren at mac.com>:

The (non-portable) pthread APIs "pthread_get_stacksize_np()" and "pthread_get_stackaddr_np()" can be used to implement PyOS_CheckStack on macOS, which would give nicer behavior than crashing when the recursion limit is too high for the stack size of the current thread.

Creating a patch should be fairly easy, but does require C knowledge.
