[New-bugs-announce] [issue16575] ctypes: unions as arguments

[Armin Rigo]

New submission from Armin Rigo:

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.
