There is also this one from cppcheck:

trunk.git/libstdc++-v3/include/debug/formatter.h:302:40: warning: Redundant
assignment of '_M_variant._M_iterator._M_constness' to itself. [selfAssignment]

Source code is

      _M_variant._M_iterator._M_constness =
      _M_variant._M_iterator._M_constness =
        __it._S_constant() ? __const_iterator : __mutable_iterator;
