    _______________________________________________________

Details:

When using Octave 3.6.4 MinGW build on Windows, executing the script below
twice crashes Octave. 
Important: a single execution works OK. It is the second execution that
results in a segfault. If "close all" is executed between the runs of the
script, everything works OK.
This bug happens with FLTK plotting (default in 3.6.4 MinGW build), gnuplot
seems unaffected.

testfigcrash.m
%---------------------------------------------------
x = rand(100, 1);
y = rand(100, 1);
z = x.^2 + y.^2;
tri = delaunay(x, y);

figure(2); clf; hold on;
trisurf(tri, x, y, z);
shading interp; axis equal; box on; colorbar;
%---------------------------------------------------

The error upon the crash is
error: base_graphics_object::get_properties: invalid graphics object
