 // Bug 717104 - Unreachable debuggee globals should not keep their debuggers

 // alive. The loop is to defeat conservative stack scanning; if the same stack

 // locations are used each time through the loop, at least three of the

 // debuggers should be collected.

 for (var i = 0; i < 4; i++) {

     var g = newGlobal();

     var dbg = new Debugger(g);

     dbg.onDebuggerStatement = function () { throw "FAIL"; };

     dbg.o = makeFinalizeObserver();

     dbg.loop = g; // make a cycle of strong references with dbg and g

 }

 gc();

 assertEq(finalizeCount() > 0, true);
