Thanks Peter, this makes sense. But just image I cannot change the print function's interface. For example I have to interface with MFC's CComboBox::AddString( LPCTSTR lpszString ) . Do you think there is still a way to have just one for_each() loop? My guts tell me no. Thanks again, Christian On 4/16/07, Peter Dimov <pdimov@mmltd.net> wrote:

The problem here is that A::name returns a temporary std::string; the code is similar to
char const * s = it->name().c_str(); print( s );
Since the temporary std::string is destroyed, s remains dangling. One way of avoiding the problem is to make print() take a std::string instead of a char*.
