[MLton-devel] yeah, that did the trick

It must be in the compuation of posInf then.

% uname 
FreeBSD 
% cat math.sml 
fun p s = print (concat [s, "\n"]) 
val _ = Math.pow (1.0, 1.0) 
val _ = p (Bool.toString (Real.== (Math.pow (3.0, 1000000.0), Real.posInf))) 
% mlton -ieee-fp false math.sml && math 
false 
% mlton -ieee-fp true math.sml && math 
true
