I made the changes you suggest. While I was previously getting -1.16e-16 and -1.03e-16 depending presence of an "extra" class member, I now get 1.11e-16 (sic not -). But it is now independent of the extra class member, which is excellent. Hopefully, things will stay that way.
This is a fairly big change to make in your program, since it completely alters the fpt semantics, but probably in a desirable way. Sounds like you don't have any real careful analysis of the reliability of the results or needed precision anyway, you just don't like the non-repeatability, and indeed the change to restrict the precision to 64-bits should work to solve that problem.
