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

[Steve Dower]

Steve Dower added the comment:

It may be exploitable, but I doubt it can be exploited without providing arbitrary Python code.

Anyone still running Python 3.3 on Windows must be building it from source. If they haven't noticed crashes from this issue yet, they aren't using the feature, and if they have they've probably already applied the patch.

I think it's Georg's call.
