Do you have a way to get a backtrace or do you want me to try?

pgaskin commented 3 years ago

It's probably something obvious, but it might save me some time (which I've been quite short of recently) if you can get one for me.

Also, on a somewhat unrelated note, do you happen to have any refreshed patches for NickelTC, specifically zlib-ng?

What's on SVN worked as of two weeks ago in x-compile, but I'd completely forgotten to update the nickel sysroot bits for zlib-ng, I'll do that.

EDIT: Done (I haven't actually run this in a while, though, stupid typos may have crept in over time).

Okay, take one, forgot that my nm binary was stripped ;p.

Taking a look at Ghidra indicates to me that this is most likely the offending bit.

// technically, we need a MoreController, but it isn't used as of 15505, so it doesn't matter (and if it ever does, it's not going to crash in a critical place)
MoreController_dropbox(nullptr);

Seems that yes, a MoreController is required as of fw 4.26.

shermp commented 3 years ago

Note, I'm having a quick stab at fixing this.
