Looks like ipa-vrp issue. I will have a look.

267 is a tad high for a char that supposedly can only go to 255.
Suspect octal 267. Probably character b7, in hex.

Output from od, if that helps

After reduction.

a;
static fn1(c) unsigned char c;
{
  if (a)
fn2(c);
  fn1('#');
}
fn3() { fn1('�'); }

The blotch character in the quotes near the end seems to have ASCII value 267.
Dunno why it's not displaying correctly.
