The kernel uses get_global_id() to index the values_out[] array.
The index is therefore related to "global work-group size" (GWS) and
belongs to [0, GWS).

Adjust the GWS so that the kernel does not reach out-of-boundary while
accessing each element of the array.

  • set the "local work-group size" (LWS) to 1 with set_group_size()
  • adjust the GWS by setting group_count = elems_nb when
    (GWS = LWS * group_count)`

Fix other tests in the same manner.
