I tried on another system and it works fine. It's definitely a problem of this machine, but not a memory corruption because I have ecc and edac-util shows 0 error corrections.

It may be a long shot, but have you tried dropping the kernel caches? Perhaps
you have a bad stick of RAM or something.

echo 3 > /proc/sys/vm/drop_caches

as root should do the trick. You may also want to do a md5sum of the hlint
binary before and after you do the above, to see if it makes a difference.
