// Test for message: operand of '%s' has invalid type '%s' [108]

/* lint1-extra-flags: -X 351 */

/*
 * Before tree.c 1.137 from 2021-01-19, taking the complement of a struct
 * (an absurd idea, by the way), resulted in an internal error because the
 * message 108 took two type operands, the second of which was not available
 * for unary operators.
 *
 * Since an error "invalid type 'none'" doesn't make sense, lint rather chose
 * to crash than to generate such an error.
