Thanks for raising the issue,
can you send the accompanying workdirn/lower.log that failed?

from hashclash.

I don't have any such file even in the successful workdirn directories.

The directory listing of a "good" workdirn:

Ah, sorry I mixed up names, it should be forward.log

No problem. I can just include that here due to its small size.

Ah, that is a surprising failure that I haven't seen before.
Unfortunately, this is not a failure of the programs,
but just unlikely with the prefix.
This can happen and you just have to make a small change and try a different prefix.
