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.
