I've pulled the newest bleeding-jumbo from github and I can't reproduce
this now, maybe it was fine back then... I'm using librexgen 1.2.5 and
now it suffers memory leak when cracking md5 hashes (--fork is only
speeding up that process). To use 1.2.6 I need to run 'git checkout
1.2.6' before running install.sh, right?
