gl-3.1-vao-broken-attrib still crashes on softpipe.

--- Comment #1 from Roland Scheidegger srol...@vmware.com ---
Hmm I guess we'd need to drop the draw call somewhere (since results are
unspecified). Not sure where the optimal place to do it is. Or invoke
out-of-bounds behavior somewhere else. I think llvmpipe (which we care about a
lot more than softpipe in general) already does this.
