Hi,

I'm getting segfaults from postfix smtpd. The same postfix configuration
worked fine on FreeBSD 9.3 i386, on fresh FreeBSD 10.1 amd64 it's
segfaulting.

# uname -a
FreeBSD mail.freebsd.systems 10.1-RELEASE-p6 FreeBSD 10.1-RELEASE-p6 #0
r279867: Tue Mar 10 23:26:11 UTC 2015
root@vesper.freebsd.systems:/usr/obj/usr/src/sys/vesper  amd64

postfix-2.11.4,1 with DOVECOT2, MYSQL, PCRE and TLS.
openssl-1.0.1_18 with ASM, EC, MD2, SCTP, SHARED, SSE2, THREADS and ZLIB

segfault is always during delivery attempt from ebay (and only from them):

Mar 19 00:10:08 mail postfix/smtpd[58326]: connect from
mxslcpool35.ebay.com[66.135.215.101]
Mar 19 00:10:09 mail postfix/master[86442]: warning: process
/usr/local/libexec/postfix/smtpd pid 58326 killed by signal 11
Mar 19 00:10:09 mail postfix/master[86442]: warning:
/usr/local/libexec/postfix/smtpd: bad command startup -- throttling

Turning off TLS in postfix fixes delivery, no segfault.

backtrace: http://pastebin.com/jDaJrqty

Is it postfix or openssl issue?
