Comment 2 for bug 1865338

Unfortunately I didn't keep that particular core dump, but I have more recent dumps. I've attached one of them. The error has changed:

[New LWP 3553]
[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 smf'.
Program terminated with signal SIGBUS, Bus error.
