[issue20160] broken ctypes calling convention on MSVC / 64-bit Windows (large structs)

[Patrick Stewart]

Patrick Stewart added the comment:

This is still a problem, and the suggested fix seems to work. There is another error a few lines above where it is allocating 4 bytes for a pointer. I've attached a new patch with both fixes, but without Bob's tests.
This issue is a duplicate of 17310
