shouldn't you also have a "unhandled signal" line here that shows what the illegal instruction was?

(you should probably have used ``` to quote all this to ensure you don't get weirdness like that fake github link too!)

fwiw, AOSP main built and booted fine for me today. you'll probably have to debug this locally to work out what the invalid instruction actually is.
