Ask questionsImmediate crash on Alpine Linux (raspberry pi 4/aarch64)

Hi there,

I'm the official packager of all libretro cores for Alpine Linux. For those who don't know, it is a linux distribution based on musl rather than glibc targetting simplicity and elegance.

I'm having a crash regarding mupen64plus-libretro-nx built from git. If I try to debug retroarch (built with debugging symbols) I'm pretty hard having a backtrace. The only way I got one was to start retroarch and open the core afterwards (using ulimit -c unlimited).

So that's the only information I could get for now:

Please tell me how can I get more information and I can help. RetroArch is at 1.9.2, Linux 5.10.36-0-rpi4 on a Raspberry Pi 4 (8GB RAM) running Aarch64.
