// Test for message: operand of '%s' has incompatible type (%s != %s) [108]

/*
 * 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 had two operands, the second of which was always NOTSPEC, as
 * could be expected for a unary operator.
 *
 * Since an error "invalid type (none)" doesn't make sense, lint rather
 * chooses to crash than to generate such an error.
