(Please keep me CC'd as I'm not subscribed to -stable) r296462 is either not ABI-compatible, or if it truly is, it breaks internal behavioural compatibility with libcrypto/libssl in some way. Building the below programs (fetchmail + postfix) from ports directly (i.e. source) **does not** fix the problem. Hope the gdb in fetchmail helps narrow down where the problem is. Don't ask me for "bt full" output, as it's pointless since none of the system libs are built with -g/-g3/-ggdb. I have no problems with SSH (unlike Mike), but that means very little given configuration differences and setups. Rolling back to r296461 (i.e. svn up -r296461) rectifies the problem fully. If jkim@ et al need a box running r296462 w/ full root to troubleshoot this, let me know and I can set one up. Might take a day or two though. $ fetchmail -a -v fetchmail: removing stale lockfile fetchmail: 6.3.26 querying mambo.koitsu.org (protocol IMAP) at Wed 9 Mar 04:55:16 2016: poll started Trying to connect to 104.238.183.73/993...connected. fetchmail: Server certificate: fetchmail: Issuer Organisation: koitsu.org fetchmail: Issuer CommonName: mambo.koitsu.org fetchmail: Subject CommonName: mambo.koitsu.org fetchmail: mambo.koitsu.org key fingerprint: F4:35:18:75:88:92:BF:1C:82:14:9E:17:EC:7E:3D:1C fetchmail: mambo.koitsu.org fingerprints match. fetchmail: Server certificate: fetchmail: Issuer Organisation: koitsu.org fetchmail: Issuer CommonName: mambo.koitsu.org fetchmail: Subject CommonName: mambo.koitsu.org Segmentation fault: 11 (core dumped) $ gdb /usr/local/bin/fetchmail fetchmail.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
