I was trying to run jtool v1-ε^6 (Gothenborg) on an iOS 64-bit executable and I'm getting a crash.

Try with NOOBJC=1 please. That should work to prevent the crash (by disabling Obj-c support). And if you can provide the exe as a sample, that would help greatly. I can quickly fix it then

Just attach it here. Or send a dropbox/gdrive link, but not one that requires login since I have login on neither. If it's hush hush use a DM, maybe?
