preprocessed testcase

when I turn on the -O optimization swith,I get the wrong result:
65535	65535	65535	65535	65535	65535	65535	65535
0	0	0	0	0	0	0	0
65535	65535	65535	65535	65535	65535	65535	65535
the correct result is :
65535	65535	65535	65535	65535	65535	65535	65535
0	65535	65535	65535	65535	65535	65535	65535
65535	65535	65535	65535	65535	65535	65535	65535
