--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
I have one another smaller test-case:

$ cat ice.i
int a;
void fn2(short, short);

void fn1(void) {
  short b[8];
  b[0] |= a & 3;
  b[1] = a;
  fn2(b[0], b[1]);
}

$ gcc ice.i -c -Og -fno-tree-fre
during RTL pass: reload
ice.i: In function ‘fn1’:
ice.i:9:1: internal compiler error: in curr_insn_transform, at
