System is arch linux.  Launching octave 9.1.0 and running the figure();
function results in a segfault and dumps core.  The following is the output
from coredumpctl info PID.  I thought that it might be related to OpenGL, so I
ran it with LIBGL_ALWAYS_SOFTWARE=1 and without.  There is no change.  Both
core.  This debug info is from a run with LIBGL_ALWAYS_SOFTWARE=1.
