# ARB_gpu_shader5 spec says:
# "The primitives emitted to all streams but stream zero are
# discarded after transform feedback. Primitives emitted to
# stream zero are passed to subsequent pipeline stages for clipping,
# rasterization, and subsequent fragment processing."
#
# This test verifies that a link error occurs if an input FS variable
# has assigned a stream > 0 in the Geometry shader.
