--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
I reduced that to:

$ cat pr109711.i
void lspf2lpc();

int interpolate_lpc_q_0;

void
interpolate_lpc(int subframe_num) {
  float weight;
  if (interpolate_lpc_q_0)
    weight = subframe_num;
  else
    weight = 1.0;
  if (weight != 1.0)
    lspf2lpc();
}

void
qcelp_decode_frame() {
  int i;
  for (;; i++)
    interpolate_lpc(i);
}

$ /dev/shm/objdir2/gcc/xgcc -B/dev/shm/objdir2/gcc pr109711.i -c -O2
