Im also seing this error in the php-fpm error logs using php 7.0.1.
I use Centos 7.2.
In my case, the segfault happens more or less each hour in every child.

Description:
------------
Using nginx with php7 fpm running invision board ipboard forum software we get a lot of SIGSEGV
errors in fpm log.
Mods enabled for that instance are : json, mysqli, opcache (not in use even) and pdo_mysql. With
opcache enabled the frequency of the crashes increases dramatically and eventually php freezes and
requires a restart to start working again. Without opcache the frequency of SEGV errors decreases
but they are still there.
Crash dumps all point to lex_scan. Here's an example dump :
Every single dump looks like this :
[New LWP 32341]
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `php-fpm: pool www
'.
Program terminated with signal SIGBUS, Bus error.
