            Bug ID: 38688
           Summary: Audit <future> for race conditions
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

As pointed out in https://bugs.llvm.org/show_bug.cgi?id=38181, there are many
places in <future> where __assoc_sub_state::__state_ is accessed without a lock
being held. We need to audit these functions to see whether we're missing
locks.
