           Summary: SetVector iterators aren't really mutable
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core LLVM classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nicholas at mxc.ca


Currently the implementation of SetVector::begin and end return iterators from
the contained vector. If someone used that iterator to modify the interior of
the vector (ala. "*MySetVector.begin() = value") then the SetVector's internal
set would be out of sync making further inserts fail or permit the insertion of
duplicates.
