Internal users reported a compiler crash when using sequential compilation. Their change involved adding a class hierarchy in which the constructor of a superclass included a RecordIndexGet. When analyzing the constructor of the subclass we also analyze the body of the super constructors. In this rare case the member being analyzed does not match the member containing the receiver node. Usually calls act as a layer of indirection that we do not analyze across. When we then save the type of the receiver, we do so in the context of the wrong member (the subclass constructor rather than the superclass constructor). We just have to be more careful to use the correct context member. The added test fails prior to this change.
