--- Comment #2 from Alex <alex at sunopti.com> ---
I put the bug here because it is caused by phobos. Ldc has added a version(ldc)
section that removes the casts to real and implements sin and cos differently
depending on precision.
if I can get around it by calling a different sin function in phobos, then I
think it is a phobos bug, but there is some interaction with the compilers
