Ah, you're right. But do you know what MFCreateAlignedMemoryBuffer is 
actually doing here? I.e., I tested calling 
MFCreateAlignedMemoryBuffer(201, 101, &buffer), but it didn't return a 
buffer aligned to 102 (such that, that is, address % 102 == 0). Do you 
know what is supposed to happen here?

I suppose we just have to mangle the alignment the proper way, without 
needing to use an additional pointer, and then we can just call 
_aligned_malloc() again.

Thanks, Giovanni.
