Using this pattern:

$ grep "func_23[^,]*,[^)]*)" bug873.c

I got the following reduced code:

struct S0 {
  int f0;
  short f1;
  unsigned f2 : 7;
  short f3
} func_2_l_27;
g_389;
func_23(struct S0 p_24, struct S0 p_25) {
  int *l_1051 = g_389;
  if (safe_sub_func_int16_t_s_s())
    for (;;)
      safe_lshift_func_uint8_t_u_s(p_24.f1);
  *l_1051 = p_25.f0;
}
func_2() {
  struct S0 l_26[] = {4, 5, 4, 6, 4, 5, 4, 6};
  func_23(l_26[1], func_2_l_27);
}

$ fgrep func_23 bug873.c
func_23(struct S0 p_24, struct S0 p_25) {
  func_23(l_26[1], func_2_l_27);
$
