When parameters 'NO_SORT' and 'Run expansion and shrinking twice' are set to unchecked, the Boundary Clean tool does not output the correct results, with the exception of the GRID format.
Non-repro with builds 6382 & 6396. Harness tests 10a, 10b, 10c pass
Also tested the original repro with the attached map package. Tiff, img and grids are all of the same size.
The bug is non-repro for me.
