Did you try to follow the advice on the LAPACK mailing list, i.e.
upgrade your compiler from the MAC OS X default (4.0.1) to 4.3.0 ?
Btw, what is the test you're running? Can you create a small test case
so I can try to reproduce it?
Thanks,
george.

Hi,
I'm developing under OSX 10.5.7 with Open-MPI 1.3.2 and am running
into intermittent corruption when send / recv user defined data type.
When running with less than four processes (i.e. mpirun -np [2,3]),
the data is fine, when running with 4 or more the received data is
intermittent
