Bug#243507: g++-3.3: broken fprintf output for floating-point formatted numbers

Package: g++-3.3
Version: 1:3.3.3-6
Severity: normal

When I use any integer constant number (e.g. '0') as an argument for fprintf
command which is '%f' formatted, the output is broken - probably uninitialized
value. When I use floating-point constant (e.g. '0.0'), everything works fine.

I am not sure if this is the problem with parsing the arguements or with
missing warnings. When I use for example simple prinf command I get the warning
during compilation.


petr@tuscan:~$ cat test.cc
#include <stdio.h>

int main()
  fprintf(stdout, "%f\n", 0);
  fprintf(stdout, "%f\n", 0.0);
  return 0;
petr@tuscan:~$ g++-3.3 -Wall test.cc
petr@tuscan:~$ ./a.out
