| Summary | 0002040: assumes clause and labels | ||||
| Description | My understanding of assumes clauses is that they refer to the pre-state of a function. The attached example, however, works differently. The function push_back has two disjoint behaviors that rely on the predicate "full". The function push_back_twice is only verified if I add the label "Pre" to the predicate "full" in the assumes clauses of function push_back. I think this is a bug. It should not be necessary to add this explicit label. | ||||
| Additional Information | Concerns versions Neon-20140301 Neon-20140301+dev-stance I remember that Kim Völlinger had observed the same(?) problem in Oxygen and that it was fixed in Fluorine. | ||||
