This is still broken in the latest 14.3 v1.0 drivers.
OpenGL Version: 4.3.12798
We've investigated the issue. We're incorrectly setting an error when this function is called outside of a debug context. If you create a debug context, it should work. We have fixed the problem in the driver and will include the fix in a future release.
Thanks for the update, it is appreciated!
Ack, Cat 14.4 WHQL are still broken with this issue...
OpenGL Version 126.96.36.19974
Mind saying which version of the openGL drivers will fix this issue ?
