It works here http://privatepaste.com/25a4861dde . I used command line:
x264 foreman_cif_352x288.yuv -o test.h264 --cqm8i 16,19,20,23,24,26,32,42,18,19,22,24,26,32,36,42,18,20,23,24,26,32,36,63,19,20,23,26,32,36,42,63,20,22,24,26,32,36,59,63,22,23,24,26,32,36,59,68,22,23,24,26,32,42,59,68,22,23,24,26,36,42,59,72
Post your full command line.
