[New-bugs-announce] [issue24048] remove_module() needs to save/restore exception state

[Davis Herring]

New submission from Davis Herring:

import.c's remove_module() is always called with an exception set and can invoke arbitrary code via deallocation; if that code calls PyErr_Clear() (or is sensitive to PyErr_Occurred()) it will lose (or be damaged by) the preexisting exception.
