2 weeks ago Summary of the core files in this CI run:
Type 1: JIT failures
These have plagued us. I'm not sure what to do, as the cores never help to debug the issue. They look like this:
Core was generated by `php -d opcache.jit_buffer_size=256M -d datadog.trace.log_file=/results/dd_php_e'.

These are sometimes truncated and sometimes not. We've been seeing these for a while. I suspect they are related to the JIT but I did not verify these specific ones are.

Description
While working on something else, I realized PHP 8.3 isn't in the randomized test framework yet.
