Reduced:

void f (char *BufPtr) {
  int Char = *BufPtr;
  switch (Char) {
    case 'a':
    case 181:
    case ~(0xff & (~180)):
      PrintError();
  }
}

$ gcc a.c -c -O2
a.c: In function 'f':
a.c:3:3: internal compiler error: in tree_low_cst, at tree.c:6569
   switch (Char) {
   ^

The regression is recent.
