ctypes should have an option to *not* catch c++ exceptions

Feature or enhancement

Proposal:

The ctypes module catches native exceptions and turns them into Python exceptions. In 99.99% of the cases this is exactly what you want, as a Python developer.

But the exception (pun unintended) is when the native exception is repeatable, but only happens in situations where you have no control.

An example is native exceptions that only occur when running your Python code which depends on numerous native libraries on the GitHub Windows runner. I have just had this happen to me for the third time in a couple of years. In the previous two cases the problem was some Python package (or native package it depends on) having a private copy of an outdated MSVC runtime library (or depending on some outdated copy). This is impossible to trace, because it is not repeatable on a development machine, and it isn't even repeatable when capturing the built folder and running the tests on you development machine.

Some mechanism (either a global method in ctypes to disable the exception-catching, or an environment variable PYTHON_CTYPES_DONT_CATCH_EXCEPTIONS) would help immensely, because I could use a debugging Python and a stack trace to pinpoint where the exception happens.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

La payload nomme le module ctypes, mais aucun fichier source ni test. Commencez par localiser le chemin natif de capture des exceptions de ctypes et examinez comment la conversion actuelle des exceptions Python est testée. Comparez un commutateur global avec PYTHON_CTYPES_DONT_CATCH_EXCEPTIONS, et définissez comme terminé le fait de disposer d’un moyen documenté et testé de préserver les exceptions natives pour le débogage sans modifier le comportement par défaut.
