+
+# Short description: A fragment shader that uses a temporary struct variable
+
+# The test passes because the fragment shader is provided with a red vec4
+# as input, and copies this through to the output (via a struct)
+
+# The following GLSL, produced by SPIRV-Cross (and then manually edited for
+# readability) shows what the shader does.
+
+# Fragment shader GLSL:
+# #version 310 es
+# precision mediump float;
+# precision highp int;
+#
+# struct S
+# {
+# highp vec4 v;
+# };
+#
+# layout(binding = 0, std140) uniform somename
+# {
+# highp vec4 v;
+# } buf;
+#
+# layout(location = 0) out highp vec4 color;
+#
+# S undef;
+#
+# void main()
+# {
+# S temp = undef;
+# temp.v = buf.v;
+# color = temp.v;
+# }
