--- Comment #5 from Reid Kleckner <rnk at google.com> ---
As discussed on the patch, I think this is actually PR31362, which is that
ms_abi just doesn't work for structs larger than 8 bytes. It uses the Linux
calling convention logic, which is wrong.

We could keep open a separate issue for making byval not generate crashing code
on win64, but I don't think it's worth it.
