--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is 1ulp difference. This is a standard issue with floating point; please
read "what every computer scientist should know about floating-point
arithmetic". The first case is the result from libm (which in Linux case comes
from glibc project) and in the second case, GCC constants folds the cbrt and
gets an exact result.
