In a thorny corner of the language C++ doesn't actually type check the return type of a function passed into a std::function argument. Here the type inference in the lambda resulted in a ChildInfo being returned where an llvm::Expected<ChildInfo> was expected, which through coincidence works very often, but not always, leading to a crash. rdar://153137542
