Description:
------------
With JIT enable php-fpm aborts after some refreshes (2 to 5 times) and keeps crashing after the first crash.

We compiled https://hub.docker.com/_/php
alpine-fpm with --enable-debug to get an idea but sadly no crash dumps are generated.

Custom extensions (+the all ready included ones)
- pecl redis
- iconv mbstring mysqli pdo_mysql curl session zip intl opcache gd imap
GD is configured with:
--with-freetype=/usr/include/ --with-jpeg=/usr/include/
IMAP is configured with:
--with-imap-ssl --with-kerberos

Config changes:
opcache.jit_buffer_size=100M
opcache.jit = tracing
opcache.memory_consumption = 128
opcache.enable = 1
opcache.revalidate_freq = 0
opcache.validate_timestamps = 0
opcache.save_comments = 1
session.save_handler = redis
session.save_path = tcp://redis:6379
session.name = SID

Test script:
---------------
---
not possible at this time, since no crash dumps are generated
---

any help appreciated to generate the dumps.
actually last attempt is:
    command: >
        sh -c "echo '/tmp/core.%h.%e.%t' > /proc/sys/kernel/core_pattern &&
        ulimit -c unlimited &&
        echo -e '\nrlimit_core = unlimited' >> /usr/local/etc/php-fpm.conf &&
        cat /usr/local/etc/php-fpm.conf &&
        php-fpm"

Actual result:
