--- Comment #1 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
This is a duplicate of 96818.  We're trying to intersect incompatible ranges
because the switch control variable type is not the same as the label type.

(gdb) p debug(switch_stmt)
switch (_10) <default: <L5> [50.00%], case 0: <L3> [50.00%], case 3: <L3>
[50.00%]>
$3 = void
(gdb) p debug(range_of_op)
int [0, 65535] <-- int
$4 = void
(gdb) p debug(label_range)
short unsigned int [0, 3] <-- short unsigned
