--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
The obviously wrong one is due to this:

       }
     case GIMPLE_SWITCH:
       val = gimple_switch_index (stmt);
       break;

(Anything in the middle-end that relies on input_location is broken.
Unfortunately, we don't have enough people to take care of cleaning up this)

The other location issue is PR63451.
