 There are still one [https://lists.osgeo.org/pipermail/grass-
 dev/2017-January/083745.html comment from Markus] that you didn't apply:
 the memory allocation for distvec. Just uncomment
 [https://trac.osgeo.org/grass/browser/grass-
 addons/grass7/imagery/i.superpixels.slic/main.c#L353 lines 353 and
 following], not forgetting to add the G_free() call later (see the patch
 in #3247). Otherwise the memory is allocated in the stack, where there
 might not be enough available, rather than the heap.

 When this is done, I agree that this ticket can be closed and we can open
 new tickets for any other problems.

 However, while you're at it: could you also consider the two additions
 proposed in that same patch of #3247, assigning a color table and adding
 the module call to the raster map's history ?
