function test()
{
debugger;

for (var i = 0; i < 1; ++i)
test();
</script>
<p>To test, open the DevTools (Ctrl+Shift+I) and reload the page. When the debugger breaks, select the
(anonymous function) node in the call stack, you should see the execution line on the call to test().</p>

Also set a breakpoint on the call to test(), and reload. It should break before the test() function is called.
