[issue46110] compile("-"*3000000 + "4", '', mode) causes hard crash

Guido, Eric, what are your thoughts here?

The fix that I merged works by limiting the maximum recursion but seems that incrementing the recursion counter on every parser call makes quite a lot of impact on startup.

Unfortunately if we revert the fix, we still have the problem that Python can segfault for certain inputs that overload the stack.
