Which leads me to another bug:

class ChubgraphStd extends Chubgraph {
	fun float
	gain(float g)
	{
		return g => outlet.gain;
	}
	fun float
	gain()
	{
		return outlet.gain();
	}
	fun float
	last()
	{
		return outlet.last();
	}
}

ChubgraphStd c;

1 => (c $ UGen).gain;

setting the gain of a UGen casted to UGen usually works, I use it in
situations like that:

UGen @gens[3];
new SinOsc @=> gens[0];
//...
10 => gens[i].gain;

but above example segfaults. It doesn't for a direct
"Chubgraph"-instance. So I guess it is a bug in ChucK's class system.

I have a bunch of test cases to segfault ChucK. Would be happy to post
them to a bug tracker of some sort...
