development trees since last year (had to wait for some intel tests to run yesterday, so I finally took the time to finish this work): * Improve MPI API argument checking by also checking for NULL values (especially helps when invalid Fortran MPI handles are passed, because the various MPI_*f2c functions are supposed to return an "invalid" MPI handle [meaning NULL] when this happens). So now OMPI will generate an MPI exception rather than a segv. * Removed a few redundant DATATYPE_NULL checks. * Also check for some other forms of "invalid" handles (e.g., already been freed, etc.) in some cases. We could probably be a bit more stringent in this regard if we really wanted to. * Change MPI_Get_processor_name to zero out the string up to MPI_MAX_PROCESSOR_NAME characters, because the MPI spec says that the string must be at least that long. We were already passing that length to gethostname(), anyway. This commit was SVN r14100.
