            Bug ID: 30898
           Summary: libc++ should (behind a macro that can enable and
                    disable) add [[nodiscard]] unique_ptr::release
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

We have a C++ annotation ([[nodiscard]]) which allows warnings when returned
values are ignored. This should be possible to enable on
std::unique_ptr<...>::release()'s returned pointer so that we don't
accidentally leak memory.
