Hello Dino,
I tried to have another look at this issue.

I found your report claims you are running testing, but
php7.3-intl 7.3.0~rc5-2 is currently just in unstable.
Are there more packages installed from unstable?
This "every nights graceful restart", is this something
you issue e.g. by a cron job?
Does the crash always happen just after 24 hours of running?
Or can you reproduce by stopping/restarting at any time?
Have you an coredump collector like systemd-coredump installed?
That would make a later inspection possible by:
coredumpctl list
coredumpctl gdb <PID>
But as the segfaults happen then in a fast flow that might put
an unexpected load to the system.
If you want to reproduce again, you might show when you reached
the segfault some of the surrounding disassembly by
disassemble $pc-0x40,$pc+40
And also what is contained in libc's fork handler:
print *__fork_handlers
print *__fork_handlers->next
Maybe also a "pstree -p | grep apache" when you have the debugger attached.
Kind regards,
Bernhard
