Details:

Example to reproduce it:

Consider the following function file:


function out = f ()
  v = 3;
  function out2 = fnested()
    out2 = v;
  endfunction
  h = @() fnested();
  h();
endfunction


and call it from octave


octave:1> f()
error: 'v' undefined near line 4, column 4
error: called from
    f>fnested at line 4 column 10
    f>@<anonymous> at line 6 column 12
    f at line 7 column 3


It was working in 5.2.0.
