> The DRLVM sometimes segfaults in optimizing modes on long comparisons, the minimal testcase
is:
> class Test {
> public static void main(String[] s) {
> long ll = 234l;
> compare(ll);
> }
> static void compare(long ll) {
>         boolean flag = false;
>         if(ll >= 0L && ll > 0L && ll > 10L)
>         {
>             flag = true;        
>         }   
> }
> }
