# Test that when an interface block contains members which are unsized
# arrays, the standard rules are applied in order to determine the
# array sizes (namely, the sizes should be inferred from the maximum
# array element accessed).
#
# In this test, the vertex shader uses an array size of 2, and the
# fragment shader uses an array size of 3, so link error should be
# produced.
