Bug reports - auth is broken in Dovecot 2.3.3

Hello, I have compiled Dovecot 2.3.3 from sources but I have problems with authentication. I tried to rebuild Dovecot 2.3.2.1 but the error persists. I attach a .txt file with the information requested to report a bug. My main mail server is fallen, (the same for the test server) I will send the report from a Gmail address. If you need additional information I will be at your disposal.
