It seems to me that this should fail, and is correctly doing so. From the
tessellation spec:
A tessellation control shader may also declare user-defined per-vertex
output variables. User-defined per-vertex output variables are declared
with the qualifier "out" and have a value for each vertex in the output
patch. Such variables must be declared as arrays or inside output blocks
declared as arrays. Declaring an array size is optional. If no size is
specified, it will be taken from the output patch size (gl_VerticesOut)
declared in the shader. If a size is specified, it must match the maximum
patch size; otherwise, a compile or link link error will occur. The OpenGL
Shading
Language doesn't support multi-dimensional arrays; therefore, user-defined
per-vertex tessellation control shader outputs with multiple elements per
vertex must be declared as array members of an output block that is itself
declared as an array.
Is there something I'm missing?
