Sorry. I always get caught in Octave's incompatibility bugs. It's not
like Octave changes that fast, Mathworks should have already fixed
this by now :p

Could you please try again and define testreadjpg as

function [out, m] = testreadjpg (filename)
  persistent im;
  if (isempty (im)); im = 1; fprintf ('im initialized\n'); end
  disp (im)
  if (im > 3), error ('stuck in a loop\n'); end
  im = im + 1;
  [out, m] = imread (filename);
end

interpretation that I'm missing :(

Thank you,
