I've tested on both i965 and swrast, it gives same result.

Eric, which discard tests are you specifically talking about ?

In case the report is confusing, 'discard' itself is not the issue here, it's
just an easily reproducible mean to notice that recent Mesa is
culling/optimizing out some (not all) back-facing (and only back-facing)
polygons that would have been over-drawn if there were no 'discard'.
