7215,string::insert returns a wrong iterator,anonymous,Ion Gaztañaga,"{{{iterator insert(const_iterator p, CharT c)}}} returns an iterator witch refers to a character behind the inserted character.

In boost/container/string.hpp:

{{{
iterator insert(const_iterator p, CharT c)
{
   size_type new_offset = p - this->priv_addr() + 1;
   this->insert(p, cvalue_iterator(c, 1), cvalue_iterator());
   return this->priv_addr() + new_offset;
