--- Comment #1 from Ian Romanick <idr at freedesktop.org> ---
I think the test is incorrect.  

Section 10.10 (Conditional Rendering) of the OpenGL 4.4 spec says:

    "If the result (SAMPLES_PASSED) of the query is zero, or if the
    result (ANY_SAMPLES_PASSED or ANY_SAMPLES_PASSED_CONSERVATIVE)
    is false, all rendering commands described in section 2.4 are
    discarded and have no effect when issued between
    BeginConditionalRender and the corresponding EndConditionalRender."

Section 2.4 (Rendering Commands) says:

    "Such commands are called rendering commands, and include the
    drawing commands *Draw* (see section 10.5), as well as these
    additional commands:

        • BlitFramebuffer (see section 18.3.1)
        • Clear (see section 17.4.3)
        • ClearBuffer* (see section 17.4.3.1)
        • DispatchCompute* (see section 19)"

It would have been much better to have these spec references in the commit
message and the in-code comments than the reference that is there.  Oh well.

Out of curiosity... Does this test pass as-is on NVIDIA or AMD?
