I think I found the problem, I filed a pr towards master, and if that
passes I will file a pr for the 2.x branch.
Thanks!

ok, but just to be able to construct a test case, basically what you are
doing is
MPI_File_write_all_begin (fh, NULL, 0, some datatype);
MPI_File_write_all_end (fh, NULL, &status),
is this correct?
Yes, but with 2 processes:
rank 0 writes something, but not rank 1...
other info: rank 0 didn't wait for rank1 after MPI_File_write_all_end so
it continued to the next MPI_File_write_all_begin with a different
datatype but on the same file...
thanks!
