I'm sorry, but this tells me absolutely nothing. If you can isolate the crash you have in a small code sample, it will help a lot, but just giving me a call stack tells me nothing, beyond that you encountered a crash.

[wenguoqing]

public function StandardMaterial(vertexShader:AbstractShader = null, fragmentShader:AbstractShader = null)
{
this.vertexShader = vertexShader || new StandardVertexShader();
this.fragmentShader = fragmentShader || new VertexColorFragmentShader();
textures = new Vector.();
colorVector = new Vector.();
color = 0xFFFFFF;
}
this args modify AbstractShader,is OK.
I don't know why.

This looks like the same issue reported here:

#68

Please have a look over there. It might help you further
