Plotter crashes sclang when changing the bounds of its parent window

[telephon]

(
a = Plotter("the plot", Rect(600, 30, 600, 400));
a.value = (0..100);

a.parent.bounds = Rect(400, 100, 500, 700); // sclang hangs, and crashes

This doesn't happen with a plain user view:

(
a = Window("the plot", Rect(100, 200, 400, 500));
x = UserView(a, a.bounds);
x.drawFunc = { this.draw };
a.front;
)

x.parent.bounds =  Rect(400, 100, 500, 700);

if I write

...
x.drawFunc = { |me|
Pen.use{
10.do{
Color.red(rrand(0.0, 1), rrand(0.3, 0.8)).set;
Pen.addArc((400.exprand(2))@(100.rand), rrand(10, 50), 2pi.rand, pi);
Pen.perform([\stroke, \fill].choose);
}
}
};
...

it works fine on mine

This is no longer an issue for me (macOS 10.11, 3.9). Can someone else test?

Working for me.

Qt update strikes again.
