I think that's happening because switching toolkits only affects new figures.  If you still have the fltk+opengl figure on the screen, the next drawnow will still use fltk+opengl.  You need to either close the existing figure or create a new one.  So try this instead:

  close all
  graphics_toolkit gnuplot

So can some of you guys can send me .gp file so I check if I

can crash standalone gnuplot?

I also tried strace, but it does not tell much:
