Bug ID: 55295
           Summary: d3dcompiler_43:hlsl_d3d11 - test_sampling() triggers
                    GLSL errors in Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: d3d

d3dcompiler_43:hlsl_d3d11 - test_sampling() triggers GLSL errors in Wine:

0668:err:d3d:wined3d_debug_callback 0166D4E8: "0:39(1): error: error index must
be >= 0".
0668:fixme:d3d_shader:print_glsl_info_log Info log received from GLSL shader
#2:
0668:fixme:d3d_shader:print_glsl_info_log     0:39(8): warning: signed literal
value `4294967295' is interpreted as -1
0668:fixme:d3d_shader:print_glsl_info_log     0:39(1): error: error index must
be >= 0

These happen at least with the QEmu and Intel GPUs (HD Graphics 4600). Because
these warnings appear in the Wine log they cannot be seen in the nightly
WineTest reports. However one can see these warnings in the TestBot's Debina
WineTest jobs, both in the summary and in the "task.log" files.

Also, to see these warnings one has to delete the shader cache since they
happen during compilation:

rm -rf ~/.cache/mesa_shader_cache/
