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.
