crash while plotting

[Jose]

Hello all.

I somehow managed to crash octave with some plotting scripts. After 
simplification, the following code reproduces the problem and crashes 
octave (versions 3.6.1 and 3.6.2) when using fltk.

----
clf;
[X,Y] = meshgrid(-2:.2:2, -2:.2:2);Z = X .* exp(-X.^2 - Y.^2);
mesh(X,Y,Z,'linewidth',1);axis('equal');colorbar;hold on;
imagesc(X,Y,Z);colorbar;
---

When using gnuplot it generates lots of of complaints but it does not crash.

The code might not make sense (with the "hold on"), but the point is 
that octave crashes

Sorry that I cannot explore further with my limitted knowledge.
