--- Comment #4 from Wan-Teh Chang <wtc at google dot com> --- Andrew: Thank you very much for the quick reply. I am also curious about the 15 number. Do you know why the compiler seems to think cfg->stage_num_col and cfg->stage_num_row can be equal to 15? I.e., why do the warnings go away if I increase the array size to 15?
