Prize for largest error message goes to STL

// HOW: cl /GX biggest_error.cpp  241 char src gives 291201 char long error message,
// AUTHOR: GPL(C)2005Mosh

#include <map>
#include <string>
#include <algorithm>
using namespace std;
void main( int argc, char *argv[] ){
    map< map<string,string>, map<string,string> > hoh; // 10K long warning message
    sort( hoh.begin(), hoh.end() ); // error line .. 280K long error message
}

Borland C++ 5.5 did a little better with 62K error message.
