Per discussion starting http://www.open-mpi.org/community/lists/users/2014/12/26018.php, at least note that OMPI does not allow adding or deleting attributes in an attribute copy or delete callback (or any of its children) on the same object on which the callback was invoked.

.SH INPUT/OUTPUT PARAMETER
|
|
.ft R
|
|

|
|
win
|
|
Window from which the attribute is deleted (handle).
|
|
|
|
.SH INPUT PARAMETER
|
|
.ft R
|
|
.TP 1i
|
|
win_keyval
|
|
Key value (integer).
|
|
|
|
.SH OUTPUT PARAMETER
|
|
.ft R
|
|
.TP 1i
|
|
IERROR
|
|
Fortran only: Error status (integer).
|
|
|
|
.SH NOTES
|
|
Note that it is not defined by the MPI standard what happens if the
|
|
delete_fn callback invokes other MPI functions. In Open MPI, it is
|
|
not valid for delete_fn callbacks (or any of their children) to add or
|
|
delete attributes on the same object on which the delete_fn callback
|
|
is being invoked.
|
|
|
|
.SH ERRORS
|
|
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.
|
|
.sp
|
|
Before the error value is returned, the current MPI error handler is
|
|
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
