ptr_map<>::insert(key, value) function is taking first argument by non-const reference. Is it missing 'const' there?
No, its an exception-safety issue. if evaluating the first expression could throw, we could leak.
Sorry to be slow, but how does const impact that -- just to prevent automatic conversion of keys from throwing?
If that's the case; wouldn't a better solution be to make insert() a template and delay the conversion until after the pointer is protected? template<class K> std::pair<iterator,bool> insert( K const& key, value_type x ); -- Daniel Wallin
