It seems for some of the fixes instead of making sure the current thread has sufficient stack space , you instead create a new thread with sufficient stack space to attach to. Is there a reason the original thread could not have been created with enough stack space?

This is failing to build on Windows. Looks like you don't have the needed #include.
