Summary:
In the new clang the parameters to these functions have notnull annotations, because of that infer tests fail. More concretely, the tests say there would be a memory leak. In the symbolic execution of those functions though, an inconsistency is created, because the parameter was nil, and the constraint argument should not be nil was also there, which leads to an error in the execution and no object is created, hence, no memory leak.
