IPhone: OpenGL-ES Crash using glDrawArrays

Question

Anyone else find that OpenGL-ES seems to want to crash when using glDrawArrays to bound to a color array? I reported it to Apple about 2 weeks ago, haven't heard anything back and it's not fixed in SDK 7.
I am trying to render an array of pixels, each their own color. So must supply a sister array of colors for each point. When turing it on using: glEnableClientState(GLCOLORARRAY); I get a crash.
Or, is there a workaround?

It does handle floats. If you read the ES 1.1 spec, it says that the size argument for glColorPointer must be 4 (Desktop GL accepts 1, 2, 3, or 4). The legal types in ES are UNSIGNED_BYTE, FIXED and FLOAT.
What is happening is the OpenGL ES implementation is properly detecting the error. If you called glGetError(), you will see GLINVALIDVALUE being returned after your attempt to call glColorPointer.
In GL, when an error is produced, the function has no other affect. In this case, the default state of ColorPointer is (size=4, type=FLOAT, stride=0, pointer=NULL). Because your call to glColorPointer effectively never happened, the pointer value stays NULL. When you call glDrawArrays, OpenGL tries to read the color data, starting at NULL.
