[mvapich-discuss] Segmentation fault at some MPI functions after MPI_Put

[Akihiro Tabuchi]

Dear Khaled,

Thank you for your correspondence.

I inserted a MPI_Win_flush before the MPI_Win_unlock but the program's 
behavior was not changed.
The segmentation fault occured at the same MPI_Win_free.

Best regards,
Akihiro Tabuchi
