I reiterate that any `errors' are much more likely to be in the code than GCC's -On optimizations if it's unstable with respect to them. > You wrote in reply to Dave > > "The optimization flags were the main cause of changes in the results, > as expected." > > I love speed but I also want to be on the correct track. Actually, re-writing unstable code might well make it faster as well as more accurate. A trivial example is double precision potentially being faster than single precision.
