Failed to compile shaders that has nested struct

[cowcoa]

Hi aras, I found the optimizer cannot correctly dealing with nested structure. e.g, the following code:

struct fragInput { highp vec4 baseTC; } struct fragPass { fragInput IN; }

will be interpreted by the optimizer as:

fragInput tmpvar_1; tmpvar_1 = fragInput(vec4(0.0, 0.0, 0.0, 0.0));

but, struct fragInput's declaration is missing. How to solve this problem?

thanks a lot.
