Runaway recursion on 3.13 and higher for _PY_FRAME_GENERAL

[Fidget-Spinner]

Bug report

Bug description:

Reported here https://discuss.python.org/t/infinite-recursion/88900

def foo(depth = None):
    print(foo.count)
    foo.count  = 1
    return foo()

foo.count = 1
print(foo())

The problem is that normal Calls check the recursion limit remaining, but _PY_FRAME_GENERAL does not.

I'm hesitant to backport the fix to 3.13, as it might break existing code.

CPython versions tested on:

CPython main branch, 3.13

Can this be closed? I think we still need the manual backport.

I think Mark intends to backport it but I'm ambivalent

@markshannon, looks like this needs a manual backport.

I marked this easy to welcome contributors to backport this to 3.13. You don't need to implement anything new, please instead see the already merged PR and follow the backport procedure here https://devguide.python.org/contrib/core-team/committing/#backporting-changes-to-an-older-version. the backport has to be manual.
