Comment 1 Roland Scheidegger 2015-01-05 17:23:26 UTC
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.

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