mupen64plus-next - bus error

I built the new mupen core on my Rockpro64 running Debian (arm64). When I try to launch, the core crashes out to CLI and says “bus error.” Is there a debug mode where I could get more information?

The core does work on lakka on this device, but I need it to do other things (host Jellyfin, Homebridge, SMB, etc) so I’m working with this. When I tried doing this in Arch, I couldn’t even get an error. Here I actually get an error, but its so vague I cant troubleshoot it. Help?
