# 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, there is a vertex shader output which an unnamed
# interface block and an array size of 2, and a geometry shader input
# that uses an array size of 2, so there should be no error.
