 *      evaluate_dereference() used to miss a call to
 *      examine_symbol_type(). This, in the present, left
 *      a SYM_TYPEOF as type for the last dereferencing
 *      which produced "error: cannot dereference this type".
 *      The presence of the __force and the typeof is needed
 *      to create the situation.
