It seems the max file size returned is limited to a 4 byte unsigned integer, even though MPI_Offset is 8 bytes. The following program fails in MPI_File_get_size for files larger than 4GB. Is there a way around this?

Just curious: are you asking this question because you are trying to use HDF5 on Windows10 with files >4Gb? Or it is another use case for which you hit this problem?

@Michael: Thanks for providing the test code. I have reproduced the issue on Windows 10 and created an internal report. I will keep this forum updated.

Id like to add that this is issue is stopping anyone using Intel MPI with HDF5 on windows with large files.
Would appreciate a getaround and/or bug fix for MPI 2017 as well.
