MASM structs are end-padded to have size a multiple of the smaller of the requested alignment and the size of their largest field (taken recursively, if they have a field of STRUCT type). This matches the behavior of ml.exe and ml64.exe. Our original implementation followed the MASM 6.0 documentation, which instead specified that MASM structs were padded to a multiple of their requested alignment.
