If retarray->data is NULL (i.e. the front end does not know the rank and dimenson of the array), fill in its properties and allocate memory. Change the assertions about rank and dimension of retarray into runtime errors and only check them for retarray->data != NULL. Do the same for correcting the stride from 0 to 1 in retarray.
