Is this a bug?

["S. Loisel" <loisel at math dot mcgill dot ca>]

I apologize for my probably impertinence. I don't know if this is a 
known bug, or if I'm just misusing something. I've got a relatively 
fresh cygwin (probably a couple of weeks old.)

$ g++ --version
g++ (GCC) 3.2 20020927 (prerelease)

The following code

#include <map>
#include <stdio.h>

int main()
{
 std::map<int,int, std::less<int> > foo;
 foo[0]=0;
 foo[2]=2;
 printf("%i %i\n",(*foo.lower_bound(1)).first,
    (*foo.upper_bound(1)).first);
 return 0;
}

produces this:

$ g++ bug.C -o bug
$ ./bug
2 2

What am I misunderstanding?

Thanks,

Sebastien Loisel
