I found a simpler case:

  function foo ()
    c = {-1, 0, 1};
    cellfun (@(x) sub2 (x), c)
    sub1 (c);
  endfunction
  function sub1 (c)
    cellfun (@(x) sub2 (x), c)
  endfunction
  function y = sub2 (x)
    y = x > 0;
  endfunction

I think the attached patch should solve the problem.

This code will probably have to change again in order to properly
handle nested functions (not planned until after 3.2).
