Description Sven Gothel 2014-01-22 09:42:36 CET

TestSharedContextVBOES2NEWT3's multithreaded tests (async 11-14)  crash
w/ a 'double free'.

It has been assured that the resource is valid and synchronized via JOGL
and the test case runs well w/ 
  - GNU/Linux +NV or AMD proprietary driver, as well as with Mesa
  - Windows + NV proprietary driver

Conclusion so far: OSX/NV driver bug in regards to multithreaded shared GL buffers ..

Type 'ANNOTATION' to document this issue, which highly likely is not ours.
