| An OpenCL memory object created from an OpenGL object |
| (hereinafter refered to as a "shared CL/GL object") remains valid as long as the |
| corresponding GL object has not been deleted. If the GL object is deleted through the GL |
| API (e.g. <function>glDeleteBuffers</function>, <function>glDeleteTextures</function>, |
| or <function>glDeleteRenderbuffers</function>), subsequent use of the CL buffer or image |
| object will result in undefined behavior, including but not limited to possible CL errors |
| and data corruption, but may not result in program termination. |

| <!-- ext. spec 9.6.1 Lifetime of Shared Objects --> |
| The CL context and corresponding command-queues are dependent |
| on the existence of the GL share group object, or the share group associated with the |
| GL context from which the CL context is created. If the GL share group object or all GL |
| contexts in the share group are destroyed, any use of the CL context or command-queue(s) |
| will result in undefined behavior, which may include program termination. Applications |
| should destroy the CL command-queue(s) and CL context before destroying the corresponding |
| GL share group or contexts. |
