To fix SCW crash I applied attached patch.
Now I was able to generate ShaderDebugInfo cache.
Attaching preprocessed USF and generated GLSL files.
The CCT command line is now:
./CrossCompilerTool …/…/Saved/ShaderDebugInfo/GLSL_150/Global/PostProcessScreenSpaceReflectionsPS00/ScreenSpaceReflections.usf -o=…/…/Saved/ShaderDebugInfo/GLSL_150/Global/PostProcessScreenSpaceReflectionsPS00/Output.glsl -ps -entry=ScreenSpaceReflectionsPS -gl3 -dx11clip -nopp -separateshaders
Attaching also CCT output.
