Hmmmm. When I checked the version, my environment was default. When I had the error, I might have been using a different build environment. These are the gcc versions I have on my system beyond 13.2.1....

Those are all the arm gcc versions I have beyond 13.2.1.
At the end of the day, I was able to build and link by removing -Werror from the makefile and it seems to be ok.

what is your git hash, maybe try to update if it isn't latest
