      Description

      The 21.string.insert.cpp test has been failing a number of assertions for self-referential test cases that exercise the ability to insert a substring of a string into itself using the insert(iterator, InputIterator, InputIterator) member template specialization for InputIterator being an actual Input Iterator. The program below reproduces the problem in a small isolated test case.

      #include <cassert>
      #include <string>

      int main ()
      {
      std::string s ("abc");

      typedef const unsigned char UChar;
      s.insert (s.begin (), (UChar*)&s [1], (UChar*)&s [2]);

      assert ("babc" == s);
      }
