Ok, I'll try to reproduce, but I would need: 1) echo ""> /tmp/ff.c && gcc -march=native /tmp/ff.c -c -v 2) please upload somewhere a sample rar archive which you use for training run 3) command line passed to ./unrar binary (are you using multiple threads?) Then it should be hopefully reproducible.
