This should be already fixed in next. You can ask Sascha to pick "commands: of_diff: simplify error handling" to master if that fixes your issue. > on the shell.

Maybe someone of the more experienced barebox devs already has an idea what's going wrong here and wants to have a closer look, otherwise I'd probably give it a shot within the next few days (and if I manage to find some spare time...) You can pipe barebox crash logs into Linux scripts/decode_stacktrace.sh to get line numbers (don't forget to set ARCH/CROSS_COMPILE). Enabling CONFIG_KASAN=y can also be very useful to pinpoint the origin of memory corruptions.
