  We obtain a (5+1)-dimensional global flat embedding of the
Gibbons-Maeda-Garfinkle-Horowitz-Strominger spacetime in Einstein frame, and a
(5+2)-dimensional global flat embedding in string frame. We show that the local
free-fall temperatures for freely falling observers in each frames are finite
at the event horizons, while the local temperatures for fiducial observers are
divergent. We also observe that the local free-fall temperatures differ between
the two frames.
