JSFunFuzz found this


Which crashes as the scope object (1->toObject()) is not protected by the
registerfile as is expected.  Looking into this i also found that we would not
correctly protect the scope when local variables are usedfor scope, as in:
var z; with(z={}){z=null; {}; {}; [1,2,3,4*{}]; gc(); b}
