Description Simon Werbeck 2015-03-14 09:22:14 UTC 
Wrong code is generated when a generic variable is captured by a lambda expression when inside the constructor. Minimal test case:

public class Test<G> : Object {
	public Test () {
		G a = null;
		SourceFunc f = () => {
			G b = a;  // capture a
			return true;
		};
	}

	static void main () {
	}
}

All this thing needs a rewrite, can't follow the code anymore :S
Comment 2 Luca Bruno 2015-03-17 10:06:14 UTC 
So the main problem is that all the code used to generate the block_data_unref, is generated in the context of the constructor, not the lambda.
