MPI_File_close causes a crash RRS feed

  • Question

  • Our app crashes on MPI_File_close() from MSMPI v10. This crash does not occur with MSMPI v8. We are using MinGW 7.3. 

    I tried to reproduce the issue with a minimal example, but the basic operations works correctly, so this is not super obvious. Is anyone else having trouble with this function?

    What would be the best way to debug msmpi library itself?

    Thanks!

  • Thanks for reporting this. Does this happen on non-MinGW environment too?

    We'll try to reproduce this, but do you have a simple reproducer?

    Also, just fyi - MSMPI is now open source, please find us at https://github.com/Microsoft/Microsoft-MPI
