[Boost-users] date _facet segmentation fault

Hello, I use this little code for formating a date value: std::stringstream l_stream; boost::gregorian::date_facet* l_format = new boost::gregorian::date_facet(); l_format->format("%Y-%m-%d"); l_stream.imbue(std::locale(std::locale::classic(), l_format)); If I call after the imbue a delete (delte l_format) to remove the date_facet from the heap the program creates a segmentation fault value. Does the std::stringstream remove the date_facet object from the heap? If not, how can I do a correct clear of the object? I hope, that question is not off topic. I would like to format a date value in a stringstream Thanks alot Phil
