The original bug was about testing the equality of doubles. I think that'sjust plain mathematically bad. Error bands should be used to test for"equality", using a band that is in accordance with the minimum precisionspecified in the compiler documentation.
To be a bit more precise: don't use the precision specified in the compiler but the precision you expect for the overall algorithms numerical stability.
