The RAR format actually has a known bug, it will sometimes fail at cmp_one(3) and I will give a beer to anyone that finds the culprit. It's present in non-OMP CPU-only builds and any other ones too. But the moment I grab my debugger, the bug crawls back under its' stone and hides until I give up. I just *hope* that if you pass the self-test, you will actually be safe running a crack, but I am not sure. I have never seen a false negative once passing self-test. BTW, cmp_one(3) indicates the problems is with normal (-m3) -p archives, that is, deflated ones without encrypted headers. So the problem *might* be within unrar.c (the clamav stuff) or the inititalization / use of it. I have gone through all of it a dozen times and I just can't find the problem. magnum
