The testcase mentioned in comment #2 is fixed but we still don't make an
infinite loop for the orginal case:
<L9>:;
switch (i_lsm.25)
{
case 0 ... 1: goto <L1>;
case 2 ... 3: goto <L12>;
case 5: goto <L5>;
default : goto <L9>;
}
<L5>:;
i_lsm.25 = 4;
goto <bb 3> (<L9>);
...
Which is obvious an infinite loop but we still go through the switch every
time.
