[Bug middle-end/22524] New: fold (or the front-ends) produces UNARY (BIT_NOT_EXPR) tree with mismatch types

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Testcase (reduced from 20020107-1.c)
char buf[10];
char * a();
int
main (void)
{
  int i = (a() - 1) - buf;
}

I will attach the patch to catch this to PR 22368.

20020107-1.c: In function 'main':
20020107-1.c:7: error: types mismatch in unary operand
intD.0
charD.1 *
~&bufD.1263;

20020107-1.c:7: internal compiler error: verify_stmts failed
