The output of my algorithm is an integer. On all other Perls tested by CPAN Testers I get the same integer. On uselongdouble Perls I usually get the same int too, but for some values I get an integer that is one off, sometimes high and sometime low. It's really just a a lucky fluke that a test happened to use a value that uncovered the bug

I may have to remove support for these "problem" Perls by aborting the build. I'd rather not do that but it's better than giving wrong results

If you're interested, there are more details in this RT ticket:
