When I ran into an issue like this, it was a result of an extension writing to memory that it
shouldn't have. Basically, the value for a string length got corrupted and then this happened.
Unless you're really comfortable with gdb, my general suggestion would be to try disabling
non-core extensions to try to narrow it down. You could also try disabling the PCRE JIT.

Unfortunately I can't seem to reproduce it to get a backtrace.
PHP modules are here: https://gist.github.com/NickStallman/f271375225a99918bd72ebfacdb58cdc
Nothing too unusual. The opcache is enabled.

HI Nick,
Please could you list the modules loaded by running php -m
Also, please could you generate a backtrace with the instructions from https://bugs.php.net/bugs-generating-backtrace.php

Description:
------------
I just had the following error which is so ridiculous it's not funny:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 5826880341616844800
bytes) in ...snip.../application/views/dns/view.php on line 4
�@Error
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 139817084080128
bytes) in ...snip.../application/views/errors/html/error_php.php on line 9
This is a CodeIgniter app, and line 4 of view.php is a echo of a single quoted string with no
variables at all.
The server config is PHP-FPM with the Ubuntu package from the ondrej PPA
1:7.1+55+ubuntu16.04.1+deb.sury.org+1
It might just be a random glitch, but I certainly found it very surprising.
Test script:
---------------
I'm having a little bit of trouble reproducing the issue, and as the error line is about an
echo I have no clue what test script would cause it.
