--- Comment #2 from Matteo Bruni matteo.mystral@gmail.com 2011-11-22 06:56:20 CST --- FWIW, I had probably the same issue with the demo on fglrx. It happens during an instanced draw and Stefan's ARB_instanced_arrays patch was a workaround (not sure if that patch is attached to any bug).
I gave it another quick look just now, apparently it crashes in send_attribute() because the gl_info->glVertexAttrib4hvNV function pointer is NULL, even though the driver reports GL_NV_half_float support. So I'd say this is a driver bug, still valid in fglrx 11.11.
