+# Tests that no link error occurs for interfaces blocks with matching

+# instanced interface blocks differ on the array dimension of the
+# interface.

+# GLSLangSpec.1.50.11, 4.3.7 Interface Blocks:
+# "The block name (block-name) is used to match interfaces: an output
+#  block of one pipeline stage will be matched to an input block with
+#  the same name in the subsequent pipeline stage. For uniform blocks,
+#  the application uses the block name to identify the block.
+#
+#  ...
+#
+#  Outside the shading language (i.e., in the API), members are
+#  similarly identified except the block name is always used in place
+#  of the instance name (API accesses are to interfaces, not to
+#  shaders)."
