problem z glGetActiveUniformsiv OpenGL

Question

static const GLchar* LightNames[] = { "LightRotate","LightRotate.rot[0]","LightRotate.rot[1]",
		"LightRotate.rot[2]","LightRotate.rot[3]" ,"LightRotate.rot[4]" ,"LightRotate.rot[5]" ,
		"LightRotate.rot[6]","LightRotate.rot[7]" };

void GetAccessToUniformBlock(GLuint prog, int n, const GLchar** names,
	GLuint* ind, GLint* size, GLint* ofs,
	GLuint* bpoint){
	GLuint ufi[32];
	*ind = glGetUniformBlockIndex(prog, names[0]);
	glGetActiveUniformBlockiv(prog, *ind, GL_UNIFORM_BLOCK_DATA_SIZE, size);
	if (n > 0) {
		glGetUniformIndices(prog, n, &names[1], ufi);
		glGetActiveUniformsiv(prog, n, ufi, GL_UNIFORM_OFFSET, ofs);
	}
	*bpoint = NewUniformBindingPoint();
	glUniformBlockBinding(prog, *ind, *bpoint);
	ExitIfGLError("GetAccessToUniformBlock");
}

Program podczas działania wykrywa błąd i uruchamia procedure ExitIfGLError. Po za komentowaniu procedury glGetActiveUniformsiv program nie wywołuje ExitIfGLError

fragment shader:

uniform LightRotate{
	mat4 rot[8];
} lightMat;
