Peter Hawkins 44596bc4ee Fix exception handling when pybind11::weakref() fails. (#3739) ... * Clear Python error state if pybind11::weakref() fails. The weakref() constructor calls pybind11_fail() without clearing any Python interpreter error state. If a client catches the C++ exception thrown by pybind11_fail(), the Python interpreter will be left in an error state. * Add test case for failing to create weakref * Add Debug asserts for pybind11 fail * Make error handling more pythonic * Does this fix PyPy? * Adapt test to PyPy differences * Simplify test to remove redundancy Co-authored-by: Aaron Gokaslan <skylion.aaron@gmail.com>		2022-02-18 14:12:00 -05:00
