    wglGetGPUInfoAMD crashing on Radeon HD 8790M

    eodabash

      This code is crashing our Dell Latitude E6540 running Windows 7 64-bit with driver version 13.250.18.0 (dated 11/29/2013).

       

      UINT n = wglGetGPUIDsAMD(0, 0);
      UINT * ids = new UINT[n];
      UINT total_mem_mb = 0;
      wglGetGPUIDsAMD(n, ids);
      wglGetGPUInfoAMD(ids[0], WGL_GPU_RAM_AMD, GL_UNSIGNED_INT, sizeof(UINT), &total_mem_mb); // crash here
      

       

      I see there was a similar report made on these forums a while back

       

      : wglGetGPUInfoAMD behavior

       

      But there's no mention of whether the problem was resolved. This code generally seems to work fine on desktop AMD cards. I've attached a simple test program that reproduces the problem.
