The example code is incorrect. Line 99:=20
   glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5*sizeof(float),
&vertices[3]);
Should be:
   glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5*sizeof(float), 3 *
sizeof(float));

(cf glVertexAttribPointer documentation: "pointer is treated as a byte=
 offset
into the buffer object's data store")

With this change the program runs correctly.

Note that even if the program is invalid it shouldn't hang the GPU. I'm wor=
king
on a fix for this.
