Description User image Christian Holler (:decoder) 2011-08-12 09:37:25 PDT
The following code crashes on jsdbg2 branch (revision 48e43edc8834, options -j -m -a -d):

var g = newGlobal('new-compartment');
var dbg = Debugger(g);
dbg.onDebuggerStatement = function (stack) { return {return: 1234}; };
g.eval("function f() { debugger; return 'bad'; }");
assertEq(new g.f(), 1234);
