Stupid me.

In the super class context is stored in a var which is the storage for a readonly property and I was assigning to the var in the init method without retaining. So I should be retaining when assigning and doing a release when calling. I don't know where I got the idea parameters passed into the init method would be consumed. Glad that's squashed.

After reading the discussion I was wondering why the analyzer wasn't complaining about the release of the context in the dealloc method of the super class since it wasn't retained on initialization. But I think that is probably asking too much of the static analyzer.
