Comment (by zooko):

 Okay, so we think this is a bug that was introduced into Crypto++ after we
 stopped updating pycryptopp's embedded copy of Crypto++ to track upstream
 Crypto++, and was then released in Crypto++ v5.6.0, and then was fixed in
 Crypto++ v5.6.1. It would be nice if we knew more precisely what bug was
 introduced and what patch fixed it, or if we at least had a reliable
 regression test that would tell us if we later introduce this bug into
 pycryptopp, but I'm not sure how to go about that and it might not be
 worth the effort.

 So, shall we close this ticket now?
