glDrawArrays causing Access Violations

I have a "terrain" class with a "draw" method. I have the following protected member variables & pointers (that apply to this problem): unsigned int width, height; GLfloat ** verts; GLfloat ** texs; ...and in my constructor, I allocate memory like so: verts = new GLfloat * [width * 2]; for(unsigned int i = 0; i < width * 2; i++) { verts[i] = new GLfloat[3]; } texs = new GLfloat * [width * 2]; for(i = 0; i < width * 2; i++) { texs[i] = new GLfloat[2]; } Later, in my draw() function, I do this: glVertexPointer (3, GL_FLOAT, 0, verts); glTexCoordPointer(2, GL_FLOAT, 0, texs); And then, later in the draw function, an access violation is produced at the following line of code: glDrawArrays(GL_TRIANGLE_STRIP, 0, width * 2); I figure I must be doing something wrong. Could anybody tell me what that thing is?

I had enabled color arrays without setting the color array pointer. So removing the call to enable color arrays eliminates the access violation.

But no triangles are drawn on the screen...

Nevermind, I just realized that I need to use a seperate call for each triangle strip.
