--- Comment #1 from Chris Rankin <rankincj@googlemail.com>  2010-03-18 13:38:56 PST ---
This test is failing in these following statements from glean/tpbo.cpp:

            glGenBuffersARB_func(1, pb_pack);
            glBindBufferARB_func(GL_PIXEL_PACK_BUFFER_ARB, pb_pack[0]);
            glBufferDataARB_func(GL_PIXEL_PACK_BUFFER_ARB,
                         windowSize * windowSize * 4 *
                         sizeof(GL_UNSIGNED_BYTE), NULL, GL_STREAM_DRAW);
            glReadPixels(0, 0, windowSize, windowSize, GL_BGRA,
                         GL_UNSIGNED_BYTE, NULL);

I am assuming that glReadPixels() is expected to write into a named buffer
object rather than a user-supplied buffer, because its final "data" parameter
is NULL. However, r600_dri.so tries to write into the "data" parameter anyway.
Hence "BANG".

Note: classic r600 driver has been abandoned.

works without any segfault with r600g (gallium driver) on my rv770
tested with mesa git master e81ee67b51651e99e7e8e52c1ccafc66835d57cd
and mesa 8.0.4

test result:
9 tests passed, 1 tests failed.
