That option's downsides are not related specifically to Emacs. The
option causes GCC to use optimizations that can produce invalid
programs. I don't think anyone has tried it with Emacs, and for a
very good reason: it is not intended for general purpose programs. I
personally advise to stay away of it, except when building programs
where you understand very well the floating-point numerical aspects of
every single line of code.
