I reformatted to our more modern style, which make the fix hard to spot, but see the comment above. The error only really shows when running large rank filters on binary images, so maybe the three year discovery time is not so bad. I checked |
I'd left the demand hint for rank as smalltile from some debugging. I've set the whole of morphology to sequential mode, which should be safe, cf. the convolution base class.
