Yes I did, forgot to mention that in my last. Most of the example code
I've seen online passes the buffer variable by reference...
I think I've gotten past the segfault at this point, but it looks like
MPI_Isend is never completing. I have an MPI_Test() that sets a flag
immediately following the M
Did you also change the "&buffer" to buffer in your MPI_Send call?

Hmm, tried changing MPI_Irecv( &buffer) to MPI_Irecv( buffer...)
and still no luck. Stack trace follows if that's helpful:
prompt$ mpirun -np 2 ./display_test_debug

Hey all,
I'm getting a segmentation fault when I attempt to receive a single
character via MPI_Irecv. Code follows:
void recv_func() {
if( !MASTER ) {
charbuffer[ 1 ];
int flag;
