[Boost-users] (no subject)

Hi,
to be compatible with a given interface I need to encapsulate a boost::gregorian::date.
I have a problem with the formatted output of the date-object.
I tried a given example:

date d(2005,Jun,25);
date_facet* facet(new date_facet("%A %B %d, %Y"));
std::stringstream ss;
ss.imbue(std::locale(std::cout.getloc(), facet));
ss << d;
std::cout << ss.str() << std::endl;
facet->format("%Y");
ss.str("");
ss << d;
std::cout << ss.str() << std::endl;

this works fine.
But the same inside an object causes an segmentation-fault:

class MyDate
{
   date m_date;
   std::stringstream ss;
   date_facet* facet;
   
   Date()
    : m_date(day_clock::local_day()),
      facet(new date_facet("%A %B %d, %Y"))
   {
      ss.imbue(std::locale(std::cout.getloc(), facet));
   }

   std::string Date::format(std::string pattern)
   {
     facet->format(pattern.c_str());
     ss.str("");
     ss << m_date;
     return ss.str();
   }
}

Can anybody tell me what Im doing wrong and how to do it better ?

Thanks a lot
