Guessing this bug /feature is introduced in CSApply ExprRewriter::buildMemberRef but didn't dig deep enough to find there. If a derived class' designated initializer initializes all stored let properties before calling super.init(), we don't properly type-check the chained init call. This does not happen if the stored properties are var or default initialized. We can however dig the OtherConstructorDeclRefExpr out of the semanticFn of the DotSyntaxCallExpr and proceed as normal.
