Details:

Not sure at the moment if this is a single bug or multiple bugs.  These are
probably inherited from the strel class and some of optimisations we do, so
they probably also affect other functions



imerode (true (3), ones (3, 3, 3))
ans =

  1
  1
  0

imerode (true (5), ones (3, 3, 3))
ans =

  0  0  0
  0  0  0
  0  0  0
  0  0  0
  0  0  0


## This should not give an out of memory, should use very small intermediary
arrays
## May be a separate bug 
%!test
%! bw = false (5);
%! bw(1:4,2:4) = true
%! assert (bwperim (bw, conndef (6)), bw)

The error comes from:

imerode (true (5), conndef(6))
error: out of memory or dimension too large for Octave's index type
