Can anybody fix this bug?

--- code: ---
#includeiostream
using namespace std;

int main()
{
  cout.setf(ios_base::fixed);
  cout.precision(3);
  cout.width(20);
  cout.fill('#');

  cout  (double)1.123456789  endl;
  cout  (double)0.123456789  endl;
  cout  (double)10.123456789  endl;
}
-

--- output: ---
###1.123
0.123
10.123
---

--- expected: ---
###1.123
###0.123
##10.123
-

It's just sad... :^(((

The snippet you posted has nothing to do with the issue discussed here, which
is about *when exactly* calling width(0) toward the end of the insertion
operation (there are minor inconsistencies in the Standard detectable when the
insertion proper throws). But in any case, per the letter of both C++03 and
C++0x , during the arithmetic insertion at some point width(0) has to be
called, normally by the num_put facet in Stage 3. Thus the behavior we are
implementing vs your snippet is already Ok, no bug to fix (if you want a
practical check, Sun Studio behaves the same).
