The lad() function needs the address of Z, (named pZ) in order to do an initial OLS. It then dereferences pZ and passes Z (of type double **) to lad_driver(). The trouble, I think, is just that gretl_rand_init() never got called, because your program didn't do libgretl_init() on startup. Note that you should also probably do libgretl_cleanup() when you're finished with libgretl.
