> 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);
> }
