Hi All,

I have xtrabackup-2.2.10, FreeBSD server 10.1-RELEASE-p16 FreeBSD 10.1-RELEASE-p16 #0: Tue Jul 28 11:41:12 UTC 2015 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC i386 and MySQL 5.6 (mysql Ver 14.14 Distrib 5.6.25, for FreeBSD10.1 (i386))

When I tried to start innobackupex I had core dump:
