There is a out-of-bounds error in Modules/_ctypes/libffi/src/x86/ffi64.c:
at line 225, classes[i + pos] can go outside the allocated memory for classes (MAX_CLASSES=4).
This code is not prepared to received "structures" with a small size (<32bytes) but where individual elements total more than 32bytes.

libffi support for unions is weak; at least ctypes should not use FFI_TYPE_STRUCT for unions.
