Frama-Clang does not complain about it at all. class A { int x; public: /*@ // y is unknown here and should be rejected ensures \result.x == y; */ A& operator=(int x) { this->x = x; return *this; } }; ### Additional Information : This refers to the Frama-Clang version obtained by Virgile on 23. May. ### Steps To Reproduce : in acslplusplus go to the directory C++Examples/OperatorOverloading and call make basic_assignment_error1.wp
