Heat, solid vise, carbide center drill, drill press
with variable speed and reversible; install left hand drill bit and back it out. If it doesn't catch, go up one size bit. If it doesn't work, you have at least removed the center section of the screw and that should've reduced the radial pressure on the threads, making it easier to remove with other tools.
Doesn't need to be red hot; just past where you can touch with bare skin.
Carefully... this is very easy to screw up.
