After I run "simple_2_crash" (with the octave w/ Markus patch v2) 
I see two figures and I can rotate/scleup and down w/o problem and w/o
warnings.

If I run un-patched octave, sometimes it crashes with

Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x00007f4e5e4b5d96 in octave::opengl_renderer::draw_patch (this=0x197ef68,
props=...) at ../libinterp/corefcn/gl-render.cc:3367
3367                  cc(0) = c(idx, 0), cc(1) = c(idx, 1), cc(2) = c(idx, 2);
[Current thread is 1 (Thread 0x7f4e55bf4380 (LWP 3656186))]

(full trace "crash2_gdb.txt" attached)
but usually it just works (Itried both optimized code and code
compiled with -O))

When it does not crash:

This looks like yet another problem.
