--- Comment #6 from José Fonseca <jfonseca at vmware.com> ---
The trace crashes on NVIDIA GL driver.

This is because you never call glEnable(PRIMITIVE_RESTART), so the driver
interprets the index 0xffffffff literally, causing a buffer overflow.


I also add to manually edit the trace and remove trailing \\ from one of the
shaders, as NVIDIA GLSL compiler fails otherwise.


AFAICS, you're getting undefined behavior because GL state is not being
properly set.
