10510,boost::uuids::uuid comparison error when used as key in std::map,cosmin.szanto@…,Andy Tompkins,"When using two almost equal uuids (e.g. the last character differs), ''a'' as a key of a std::map and ''b'' as parameter for the '''find''' function, the function will return that elements ''b'' is found in the map.

A simple test to reproduce the bug:
{{{#!c++
#include <map>
#include <iostream>

#include <boost/uuid/uuid.hpp>
#include <boost/uuid/string_generator.hpp>

int main() {
  boost::uuids::string_generator gen;
  boost::uuids::uuid a = gen(std::string(""145cfc95-8050-455a-8382-44ca57c1483b""));
  boost::uuids::uuid b = gen(std::string(""145cfc95-8050-455a-8382-44ca57c1483c""));

  std::map<boost::uuids::uuid, int> elements;
  // Adding element 'a'
  elements.insert(std::make_pair(a, 1));
  // Element 'b' is found although is not added.
  std::cout << ((elements.find(b) != elements.end()) ? ""Found."" : ""Not found."") << std::endl;
  return 0;
}
