2144	The OpenGL binding uses withCAStringLen where it should use withCAString	guest		In the module `Graphics.Rendering.OpenGL.GL.Shaders` (and possibly in other parts of the OpenGL binding, I didn't check) when passing a string to the OpenGL drivers, the library always uses `withCAStringLen` to marshal the strings, which does not put the required the zero byte at the end of the string. This causes the functions `getAttribLocation`, `bindAttribLocation` and `uniformLocation` to fail randomly (it was a real pain to localize this bug...). The solution is to use `withCAString` in these cases instead (and meantime, as a workaround, to put the zero character there manually in the client code). 	bug	closed	normal		libraries (other)	6.8.2	invalid		bkomuves@…	Unknown/Multiple	Unknown/Multiple		Unknown
