Thanks for the stack backtrace! According to that and the PHP version, the segfault occurs on this
line:
https://github.com/php/php-src/blob/9bc17e44be7577ad8dcf325e9a8e104b58e098a5/ext/opcache/ZendAccelerator.c#L2252
Can you please confirm?
If so, that hints at a memory corruption, since
entry can't be null there, but
apparently entry->parent is not set to valid memory.
