Fix vis family of functions to not leak The code uses an internal helper function to avoid code repetition. But to get there, the function takes a pointer to a pointer, so that the few functions that require returning an allocated buffer can get hold of it this way. The problem is that the user might pass a NULL pointer and trigger an internal allocation even if the functions are not expected to do so. Add a new internal helper for non-allocations, that will assert that condition, and make any other function that requires this behavior call this one instead. Warned-by: coverity
