Hi Adrian,

I was just able to test it using an upgraded Debian Sid ppc64:

It crashes because of:

Thread 1 "firefox-esr" received signal SIGSEGV, Segmentation fault.
i32_load8_u (addr=2014643200, mem=<optimized out>) at rlbox.wasm.c:146
146	rlbox.wasm.c: Datei oder Verzeichnis nicht gefunden.

Backtrace attached.

Regards
Johannes
