This is, indeed, an issue in the release and not just in any particular
operating system. The change (in 1.8.0) was to add a couple more digits to the
output of floating-point numbers (DBL_DIG + 2 instead of just DBL_DIG, for
those who know what that means). I was trying to be sure of getting all of the
information in the number, especially for DB saving, but I may have gone too
far. I'll look into it for 1.8.0p2.
