ctypes pretends to support passing arguments to C functions that are unions (not pointers to unions), but that's a lie. In fact, the underlying libffi does not support it. The attached example misbehaves on Linux x86-64. |

A minimal fix would be to update the documentation. A more comprehensive fix would be to tweak ctypes to reject unions and bit-fields when running on non-x86 (does this work for ARM and other non-Intel archs?) An even more comprehensive fix would be to make this work, but that would require forking libffi and should presumably be first implemented upstream. |

I've opened a libffi issue in an attempt to get this fixed upstream: https://github.com/atgreen/libffi/issues/33 |
