# From the GLSL 1.50 spec, section 4.3.7 (Interface Blocks):
#
# Matched block names within an interface (as defined above) must
# match in terms of having the same number of declarations with
# the same sequence of types and the same sequence of member
# names, as well as having the same member-wise layout
# qualification (see next section). Furthermore, if a matching
# block is declared as an array, then the array sizes must also
# match (or follow array matching rules for the interface between
# a vertex and a geometry shader).
#
# This test verifies that trying to link a VS output interface array
# to an unsized GS input interface array fails, even if the implicit
# size of the GS input interface array matches the explicit size of
# the VS output interface array.
