It looks like MPI_Cart_create argument checking was fixed in 1.3.4
but not MPI_Graph_create.

vayu1:~/openmpi-1.3.4 > diff -w -u ompi/mpi/c/cart_create.c ompi/mpi/c/graph_create.c

...

-int MPI_Cart_create(MPI_Comm old_comm, int ndims, int *dims,
- int *periods, int reorder, MPI_Comm *comm_cart) {
+int MPI_Graph_create(MPI_Comm old_comm, int nnodes, int *index,
+ int *edges, int reorder, MPI_Comm *comm_graph)
+{

...

+ if ((0 > reorder) || (1 < reorder)) {
