Yep, good catch. >> If you wrote to the file with a C++ program, then I guess the >> compiler aligned the data so that the whole struct is 128 bytes >> in size.

The C++ compiler must treat > POD structs essentially as if they are C structs. Correct me if I'm wrong. But as far a I know the C standard also allows arbitrary alignment.
