    A lot of combinations and trials have been done, yet to no avail.
    Intel v11.0 worked...

    Thanks to Hubert Haberstock (Intel) providing the hint in:
    http://software.intel.com/en-us/forums/showthread.php?t=87132

    This was tested on openmpi-1.5.4 and therefore should
    cmr:v1.5

This commit was SVN r25290.
