OpenGL: GL_OUT_OF_MEMORY error from glUseProgram.

[Evan_O_]

I'm seeing a problem with a particular set of shaders that pass structs as 'out' parameters to functions. On a system with Intel Iris 6100 graphics the resulting program generates an OUT_OF_MEMORY error when it is bound with UseProgram. On Nvidia and AMD graphics there is no problem.

I'm attaching a sample program that contains a vertex and fragment shader pair that shows the problem. The application attempts to build a program from them and calls UseProgram and then checks for errors. In debug you should see an assert fire (asserting that there was no error). 

I'm testing this on Windows 10 64-bit with driver version 10.18.15.4281.

Thanks,

Evan

Hi Evan,

Thanks for the additional info, I am talking with the OpenGL driver development team and have a ticket filed. We will investigate and find out what is going on.

Hi Evan,

Do you have a working binary sample for this issue? When we build and run the program nothing is happening, we may be missing some support files.

Attached, make sure the vs.txt and fs.txt files are in the same directory as the exe when you run it (or in the Visual Studio working directory if running from the debugger). The only output will be an assert dialog that glGetError == NO_ERROR.

Got it. Thanks!

Hi Evan,

We found the root cause and fixed the issue in out driver. Now we may not have gotten the fix checked in early enough to make it into the upcoming driver release. So it may not be in the next driver release but the following one.

Awesome, thanks for the update!
