That's odd, can you name a format? This should be impossible since we do 
things like:

	max_group_size = get_kernel_max_lws(sequential_id, crypt_kernel);
	for (optimal_work_group = my_work_group = wg_multiple;
	        (int)my_work_group <= (int)max_group_size;
	        my_work_group += wg_multiple) {
