// Section 4.3.8.1 (Input Layout Qualifiers) of the GLSL 1.50 spec
// includes the following examples of compile-time errors:
//
// // code sequence within one shader...
// in vec4 Color1[]; // size unknown
// ...Color1.length()...// illegal, length() unknown
// in vec4 Color2[2]; // size is 2
// ...Color1.length()...// illegal, Color1 still has no size
// in vec4 Color3[3]; // illegal, input sizes are inconsistent
// layout(lines) in; // legal, input size is 2, matching
// in vec4 Color4[3]; // illegal, contradicts layout (*)
// ...Color1.length()...// legal, length() is 2, Color1 sized by layout()
// layout(lines) in; // legal, matches other layout() declaration
// layout(triangles) in;// illegal, does not match earlier layout() declaration
//
// This test verifies the case marked with (*), namely that an error
// results from declaring a geometry shader input with an explicit
// array size that is inconsistent with a previous layout declaration.
// This test verifies the case for input interface blocks.
//
// [config]
// expect_result: fail
// glsl_version: 1.50
// check_link: false
// [end config]
