From 9c9395071c754d1d642be09abb3518cc08cd6b45 Mon Sep 17 00:00:00 2001
From: Albert Cheng <acheng@hdfgroup.org>

Subject: [svn-r10640] Purpose: Bug fix.

Description:
When there were errors in the test, program still just call MPI_FINALIZE
and failed to attempt to exit with some error code so that calling
programs like make be informed of the exceptions.

Solution:
Call MPI_ABORT if error is detected. Though MPI_ABORT does not
guarantee 100% failure report, it has the best chance.
Also made dimension incompatible as a real error.

Platforms tested:
Did not h5committest but tested in heping PP only since this
is a simple fix.
