Another example. Py_ReprLeave() function can be called while an exception is set. I'm not sure that it is "safe" to call new code while an exception is set. The function can raise a new exception. For example, PyList_SetSlice() can fail because of a MemoryError. I modified Py_ReprLeave() to save and then restore the current exception: http://hg.python.org/cpython/rev/28ff7ac91477 If Py_ReprLeave() raises a new exception, it is clears (replaced by the previous exception context).
