Presence of empty function "CudaTest(char* msg)" causes segmentation fault.

`
frontiers_len += h_nitems;

depth_index.push_back(frontiers_len);

bc_forward<<<nblocks, nthreads>>>(m, d_row_offsets, d_column_indices, d_path_counts, d_depths, depth, d_changed, d_visited, d_expanded, d_nitems, d_frontiers, frontiers_len);

CudaTest("solving bc_forward failed");

bc_update <<<nblocks, nthreads>>> (m, d_depths, d_visited);

CudaTest("solving bc_update failed");
`

Removing these function calls work for me.
