Infinite loop/allocation on costCenters

[ndmitchell]

Given https://gist.github.com/ndmitchell/213f9d0a0919c23b80fb3c75c1178657, if you parse it with decode you get a valid value (even though it has trailing garbage at the bottom, e.g #12). But if you then call costCenters it loops forever. I suggest that costCenters should be robust to any input.

Thank you for the report! I’ll take a look.
