Or maybe Thomas can run a bisect ? Thomas, do you feel comfortable with
doing this ? There are a few patches between 4.1.17 and 4.1.18, in 8
steps it should be done, and only 4 if you limit yourself to the crypto
directory. Stable versions are fast at bisecting because each patch
touches a very isolated area so only the first build takes a bit of
time but the other ones are often pretty fast. Finding the faulty
patch can help spotting if something is wrong in its backport.

Regards,
Willy
