[Octave-bug-tracker] [bug #55648] [MXE-Octave] cannot print with gnuplot graphics toolkit

[Markus Mützel]

Follow-up Comment #10, bug #55648 (project octave):

The problem is probably the use of "pause" at around line 120 in
__gnuplot_get_var__:

      while (isempty (str))
        str = fread (istream, "*char")';
        if (isempty (str))
          pause (0.05);
        else
          str = regexp (str, 'OCTAVE:.*', "match");
          str = str{end}(8:end);
        endif
        fclear (istream);
      endwhile


That allows the event queue being flushed that at that point seems to contain
another call to this function. If I delete the pause command, printing works.
But that might block other things.

CC'ing Dan Sebald as the expert for the gnuplot graphics toolkit.
