Bug 25999

piglit/tests/glslparsertest/shaders/CorrectConstruct.vert:

struct s2 {
    float f;
    struct s3 {
       int i;
    } s3Inst;
} s2Inst = s2(1.0, s3(1));

gets Error: s3: undeclared function name


Similar error happens on CorrectConstFolding1.vert and CorrectConstFolding2.vert.


I can't find similar example in GLSL spec, but http://staffwww.itn.liu.se/~jimjo/courses/TNCG14-2009/documents/GLSLfeatures-110.pdf section 1.3 has this valid example (very similar to piglit cases):

struct light
{
    vec4 position;
    struct tLightColor
    {
        vec3 color;
        float intensity;
    } lightColor;
} light1 = light(v, tLightColor(color, 0.9));
