1 // Bug 717104 - Unreachable debuggee globals should not keep their debuggers 2 // alive. The loop is to defeat conservative stack scanning; if the same stack 3 // locations are used each time through the loop, at least three of the 4 // debuggers should be collected. 5 6 for (var i = 0; i < 4; i++) { 7 var g = newGlobal({newCompartment: true}); 8 var dbg = new Debugger(g); 9 dbg.onDebuggerStatement = function () { throw "FAIL"; }; 10 dbg.o = makeFinalizeObserver(); 11 dbg.loop = g; // make a cycle of strong references with dbg and g 12 } 13 14 gc(); 15 assertEq(finalizeCount() > 0, true);
