--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Simplified example:
```
int array[104];

int f(int t)
{
        return array[t];
}
```

Compile this at -fprofile-arcs  -O2 -fsanitize=bounds and in .optimized we
have:
```
  PROF_edge_counter_5 = __gcov0._Z1fi[0];
  PROF_edge_counter_6 = PROF_edge_counter_5 + 1;
  __gcov0._Z1fi[0] = PROF_edge_counter_6;
  # DEBUG BEGIN_STMT
  _11 = (sizetype) t_1(D);
  if (_11 >= 104)
    goto <bb 3>; [0.05%]
  else
    goto <bb 4>; [99.95%]

  <bb 3> [local count: 536864]:
  _12 = (unsigned long) t_1(D);
  __builtin___ubsan_handle_out_of_bounds (&*.Lubsan_data0, _12);

  <bb 4> [local count: 1073741824]:
  PROF_edge_counter_7 = __gcov0._Z1fi[1];
  PROF_edge_counter_8 = PROF_edge_counter_7 + 1;
  __gcov0._Z1fi[1] = PROF_edge_counter_8;
  _4 = array[t_1(D)];
```

But we do really need to profile that arc?
