1 // The arguments can escape from a function via a debugging hook.
3 var g = newGlobal();
4 var dbg = new Debugger(g);
6 // capture arguments object and test function
7 dbg.onDebuggerStatement = function (frame) {
8 var args = frame.older.environment.parent.getVariable('arguments');
9 assertEq(args.missingArguments, true);
10 };
11 g.eval("function h() { debugger; }");
12 g.eval("function f() { var x = 0; return function() { x++; h() } }");
13 g.eval("f('ponies')()");
