----------------------------------+-----------------------------------------
 ptr_map::mapped_type seems incorrect. It's int* instead of int.

 {{{
 #include <boost/ptr_container/ptr_map.hpp>
 #include <map>

 template <class T, class U>
 typename T::mapped_type* find_ptr(T& c, U v)
 {
         typename T::iterator i = c.find(v);
         return i == c.end() ? NULL : &i->second;
 }

 int main()
 {
         typedef boost::ptr_map<char, int> c1_t;
         std::map<char, int> c0;
         c1_t c1;
         int* p0 = find_ptr(c0, 'x');
         int* p1 = find_ptr(c1, 'x');
         return 0;
 }
 }}}
