[issue35269] A possible segfault involving a newly-created coroutine

[Zackery Spytz]

New submission from Zackery Spytz :

If compute_cr_origin() fails in PyCoro_New(), coro->cr_origin won't be 
initialized. This will cause a crash during the coroutine's deallocation.

I'll create a PR for this issue.
