    _______________________________________________________

Details:

Appended code produces Octave crashes on windows.

Octave 4.4.1-rc1 and v4.4.0 and possibly older versions.

Sometimes everything is ok.

Sometimes octave crashes and ends.

Sometimes octave crashes at the first run. Sometimes after the 10. run. Just
press F5 several times...

Sometimes octave crashes with a message from windows : octave-gui.exe has
stopped working.

Crashes are more frequent when using gnuplot or fltk graphic toolkit.

Crashes seem to happen only with GUI (I could not produce a crash with CLI).

Sometimes some errors (as shown below) at random position but always after or
at line 98:


    error: bool cannot be indexed with {
    error: parse error
    error: called from
        size at line 57 column 5
