Question

From backtrace i found this line and i dont understand what is happening here. int UNUSED() function is called and from description i read that it is returning void. Why? I believe that could be the reason of crashing.

Hi,

I think you are right. The p_sbc cannot be UNUSED.

Thanks Abner
