Dear all,

There has been a mistake in my mail; that is, I am using mpich2-1.2 
(not mpich2-1.1.1p1).  After googleing more about my error message, I 
found the page https://trac.mcs.anl.gov/projects/mpich2/ticket/838, 
which seems to deal with similar problems, but as far as I understand, 
the fix mentioned there is already included in mpich2-1.2, isn't it?

Any help is greatly appreciated.

Best Regards,

Tim
