MPICH is reporting that your call to MPI_Gather is not valid. Your src_buf and recv_buf are the same buffer, which is not allowed. Also, what Wesley said. :) ~Jim.

This mailing list isn't the correct place to ask questions about using MPI. This is for asking questions about standardizing MPI. I'd encourage you to repost your question on discuss(a)mpich.org and you'll get assistance with MPICH there.
