Content
This change is motivated by my PR 28128 which converts the Py_TYPE() macro to a static inline function. The problem is that by default, MSC disables inlining and test_exceptions does crash with a stack overflow, since my change increases the usage of the stack memory: see bpo-44348. By the problem is wider than just Py_TYPE(). See also bpo-45094: "Consider using __forceinline and __attribute__((always_inline)) on static inline functions (Py_INCREF, Py_TYPE) for debug builds".
