I'd be very pleased if somebody would supply that data.  Because a new
MCI_INTEGER64 type would make the parser more regular and simplify my patch.

Go to WTB job 1156 before it gets deleted, you can download both patch and exe.

Your results are crazy indeed.  Perhaps MS auto-detects a 32bit driver and
sends plain old DWORD-sized objects instead?!? That also hints in the direction
of additional MCI_INTEGER64 types.
Austin English machine's shows exactly the crash that one expects from a
32/64bit pointer mismatch:
