Fun with floating point

[Kenny via Digitalmars-d-learn]

The above code snippet works correctly when I use LDC compiler 
(it finds expected 'f' value and prints it to console). I'm 
wondering is it a bug in DMD?

p.s. the final code used by both compilers:

import std.stdio;
import std.conv;

int main(string[] argv)
{
     const float eps = 1.0f;
     float f = 0.0f;
     while (f + eps != f)
         f += 1.0f;

     writeln("eps = ", eps, ", max_f = ", f);
     return 0;
}
