Crash with OPTION ARB_position_invariant ?

[execom_rt]

Try with a Powerbook G4 17" with GF4 MX, OS 10.3.5

Load OpenGL Shader Builder (in Developer/Applications/Graphics Tools)

Type this code in the ARB_vertex_program panel
--<Start code > ----------------
!!ARBvp1.0 OPTION ARB_position_invariant;
END
---<End code>--------------
The application crashes :???: . In fact. All application using it will crash.

Can someone can try the same thing, in order to verify ?

Thanks;
