> The following test causes VM crash. I've marked this issue as critical because it seems to be a regression and causes an error of the functional test http://people.apache.org/~smishura/r602572/Linux_x86/func/functional/org/apache/harmony/test/func/jit/HLO/peel/LoopVar2/738_LoopVar2.html
> public class Test {
> boolean flag = false;
> public static void main(String[] args) {
> System.exit((new Test()).test());
> }
> public int test() {
> int limit = 100000;
> int i = -1;
> int k = -1;
> while (k < limit) {
> k++;
> for (i = 0; i < k; i++) {
> flag = true;
> }

> return ((k == limit) && (i == limit)) ? 0 : 1;

> SIGSEGV in VM code.
