Description:
------------
Ever since upgrading from PHP 7.0.22 to 7.1.8 (first installed via the FreeBSD package manager and later recompiled myself to build with symbols to debug this problem), I've been having a semi-reproducible SIGSEGV in the php-fpm processes that brings down all php-fpm instances and kills the service.

This repeats with an odd regularity, every day or every other day at either ~11:20pm or ~12:20pm CST.

This is the stack trace from the master process as retrieved from the core dump:

The following is an additional backtrace that might be 100% wrong as it is from a coredump generated by the packaged version of PHP-FPM analyzed with the symbols from my own php-fpm build:

After the initial crash of a child process, subsequent _automated_ restarts of worker processes by the main php-fpm process fail, all immediately SIGSEGVing upon restart. Once a new php-fpm master process is started up, everything continues OK.

Here's what the log looks like:
