[Matteo Bruni]

Eventually they will be split or otherwise transformed before getting
here.

I don't feel strongly about the compiler error question, but as it turns 
out I already have a patch locally which splits array copies.

It's not the end of the world since it's been like this for a while
and this compiler is not plugged in Wine yet, but this patch does
avoid asserting when compiling some shaders.
