Fatal Error When Idle "UnsafeMutablePointer.initialize overlapping range"

[AugustSaintFreytag]

I've built a listener server with Perfect HTTP, listening on certain routes for Webhooks called by GitLab on certain repository actions. The project is a work in progress and primarily for my own use, though it is public on https://gitlab.com/apricum/gitlab-listener.

I'm starting the server through systemd via systemctl start and the likes. I've found it crashes after a seemingly random amount of time, sometimes a few hours, other times not even ten minutes. Reading the log with sudo journalctl -u gitlab-listener (where gitlab-listener is the name of the systemd service file), as follows:
