full argument checking (allowing that MPI_PROC_NULL is legal, of course). Only after the argument checking do we shortcut. Fixes trac:237, which was caused by moving the MPI_PROC_NULL test in MPI_Bsend_init, but not allowing for MPI_PROC_NULL when checking rank. This commit was SVN r11108. The following SVN revision numbers were found above: r10972 --> open-mpi/ompi@31c66d92aa The following Trac tickets were found above: Ticket 237 --> https://svn.open-mpi.org/trac/ompi/ticket/237
