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?
This is for Windows 10, mpicc.bat for the Intel(R) MPI Library 2018 Update 2 for Windows*

Attached program shows the issue.
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.
