I cannot reproduce such behaviors here with my h264enc script using
2pass mode. My mencoder is r29428 and x264 is r1189M (patch with NAL
HRD patch, hence the 'M' at the end of its version). Both are compiled
using gcc 4.3.2. It is know that gcc 4.4.0 can produce faulty binaries
but I just mention this since I don't know if you used this version to
compile your bins. There's definitely something wrong on your side.
