[Bug 304856] [NEW] Example use of plot3d crashes maxima

[vandys]

Public bug reported:

Binary package hint: maxima

Using one of the "? plot3d" examples appears to crash Maxima.  Notice that it ends up so messed up that the
last "? version" query actually segv's right out of the application.  This is Maxima 5.13.0 under a fully updated Kubuntu Ibex.

(%i2) expr_1: 5*cos(x)*(cos(x/2)*cos(y) + sin(x/2)*sin(2*y)
                + 3.0) - 10.0$

(%i3) expr_2: -5*sin(x)*(cos(x/2)*cos(y) + sin(x/2)*sin(2*y)
                + 3.0)$

(%i4) expr_3: 5*(-sin(x/2)*cos(y) + cos(x/2)*sin(2*y))$

(%i5) plot3d ([expr_1, expr_2, expr_3], [x, -%pi, %pi],
                [y, -%pi, %pi], ['grid, 40, 40]);

Maxima encountered a Lisp error:

Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
