Seems like DMD's floating point issue. The issue being that it always 
works with floats as full-width reals + rounding. Basically if nothing 
changed (and I doubt it changed) then  DMD with floating point code is 
about two (or more) times slower then GDC/LDC.

The cure is using GDC/LDC compiler as they are pretty stable and up to 
date on the front-end side these days.
