Message 278759 - Python tracker

At least for non-Darwin POSIX builds:
* Building _ctypes with the bundled copy of libffi is deprecated in 3.6 and the default is to use a system copy of libffi, issue 27976.
* The bundled libffi is removed in 3.7, issue 27979.

As this crash happens with the bundled libffi, closing this issue as won't fix.
