Thanks for reporting these two issues. These two patches (attached) address your test case, but it's a part of the code I don't play in often, so I'm going to need a review on them before committing:

Rob, I think you patch 2 is not right. It will endup calling the error handler set in COMM_WORLD. So if you set the FATAL errhandler in a file, but the RETURNS in comm world, then things will not work as expected.

I think a better approach would be to somehow call

handleFatalError(NULL, "MPI_File_call_errhandler", errorcode);

in errutil.c, but that would require some code refactoring to access that function.

I've done that refactoring -- possibly not in the most MPICH-y of ways -- in the attached patch 0002 ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA
