Subject: [PATCH] glsl/linker: Avoid buffer over-run in
 parcel_out_uniform_storage::visit_field
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

When too may uniforms are used, the error will be caught in
check_resources (src/glsl/linker.cpp).

NOTE: This is a candidate for the 8.0 branch.
