Problem with extensions on ATI Radeon


I’m having trouble using the GL_OCCLUSION_TEST_HP extension on my ATI Radeon 9700 Pro. Whenever I call glEnable(GL_OCCLUSION_TEST_HP), the driver crashes the program by emitting a TRAP signal.

Is there anything I need to do in order to use OpenGL extensions? I have installed the latest ATI driver for Linux, and glxinfo reports both hardware acceleration and the extension.
