### Description :
In the attached example, there is one unverified precondition.
[wp] Proved goals: 38 / 39
Qed: 60 (0ms-1ms)
Alt-Ergo: 18 (15ms-81ms) (58) (unknown: 1)
Coq: 0 (unknown: 6)
cvc4: 9 (30ms-50ms) (interruped: 1)
If I understand it correctly, then drama-clang/wp cannot establish that the object on which
the method "get" is called is properly constructed.
In my opinion everything is fine.
### Steps To Reproduce :
Go to acslplusplus/C++Examples/OperatorOverloading and call
"make basic_assignment1.wpgui"
