I think few more test can be added to test same number of declarations and
same sequence of member names and types.
e.g.
[vertex shader]
uniform block {
       vec4 a;
       float b;
       int c;
} inst_a;

[fragment shader]
uniform block {
       float b;
       int c;
       vec4 a;
} inst_b;

as per spec this should not work.
