I'm seeing the same segfaults on ubuntu 14.04 without joomla. We get about 1 segfault per 2k
requests, seamingly random. I can't pin it down to a single call. The only common thing in the
backtraces seems to be zend_alloc.c:1306.
Additional fun fact: if I install the newrelic php extension, the segfaults seem to go away.

Software used:
* Ubuntu 14.04, kernel 4.4.37
* nginx 1.4.6-1ubuntu3.7
* php-fpm 7.0.15
* php modules: apcu, calendar, Core, couchbase, ctype, curl, date, dom, exif, fileinfo, filter, ftp,
gd, gettext, gmp, hash, iconv, igbinary, json, libxml, maxminddb, mbstring, mcrypt, memcached,
mysqli, mysqlnd, openssl, pcntl, pcre, PDO, pdo_mysql, Phar, posix, readline, redis, Reflection,
session, shmop, SimpleXML, soap, sockets, SPL, standard, sysvmsg, sysvsem, sysvshm, tokenizer, xml,
xmlreader, xmlwriter, xsl, Zend OPcache, zlib
