I suspect, but haven't had time to confirm, that this bug would be fixed by the proposed patch in 714583.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=714583 Essentially BLACS internally needs to convert MPI Communicator handles between C and Fortran. Many MPI implementations, like OpenMPI, provide routines for this conversion (MPI_Comm_f2c / MPI_Comm_c2f) but due to to the BLACS build flags these routines are not used. -Brad -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
