This is probably NOT common but just to make sure, are you using the
default Virtual File Driver (VFD) when reading on windows? If not, that
could be your problem. This is something you would control via file
access property lists. H5Pset_fapl... or some such call.

For example, I had code developed on linux that set the stdio VFD by
fiat. When it ran on Windows, that meant it was using stdio VFD there
too. But the stdio VFD was really intended for linux. It *should* work
fine on windows but I didn't want to chance it. So, I added #if _WIN32
compilation logic to NOT set VFD when on windows.
