            Bug ID: 16253
           Summary: SmallVector not safe to insert elements into itself
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Support Libraries

See 183465 and r183459 for an issue that arose because of this (& please revert
that fix once this issue is addressed)

r178319 discusses a similar issue with vector wehre Howard Hinnant decreed that
it was conforming & didn't add overhead to the vector implementation to do so -
so we should do the same thing with SmallVector to avoid surprise
