We're getting segmentation faults from php-fpm whenever the php8.1-xdebug extension is enabled. This issue occurs consistently within our docker container built on the arm64v8/ubuntu base image. The docker engine is running on a macOS Ventura host. We get the following stack trace from the core dump:
