try with:
USE_ZEND_ALLOC=0 ZEND_DONT_UNLOAD_MODULES=1 valgrind php7 yourscript.php
it will shows where the problem came from, and I guess it probably relates to YAML.

Unfortunately I wouldn't be able to test it without YAML, this is on a live server. There doesn't seem to be a huge amount of rhyme or reason to the actual scripts that are crashing it. I've had a case where the same script, with slightly different database inputs ie. a different record is crashing it.
I've also downloaded the database to my local machine, run the script on local (mac running same version, though not compiled) and it hasn't crashed.

Hi michael!
Do you get this segfault as well with YAML not installed? What version of YAML do you have installed. Is there a specific script that is causing this, if so are you able to post it?
thanks

'--prefix=/usr/local' \
'--with-libdir=/lib/x86_64-linux-gnu' \
'--with-mysqli' \
'--enable-fpm' \
'--with-readline' \
'--with-pdo_mysql' \
'--with-curl' \
'--enable-pcntl' \
'--enable-mbstring' \

'--with-png-dir=/usr' \
'--with-jpeg-dir=/usr' \
'--with-freetype-dir=usr' \
'--with-ttf' \

also has PECL YAML extension installed.

Clean shutdown
Actual result:
