TWIMC, there is another report about this in this thread (sadly some of
its post did not make it to lore):

This doesn't fail on x86-64 when I build it.  I also did a cross-compile to
arm64 with the arm64 defconfig, and it doesn't fail there either.

I'm guessing this is a compiler version thing.  I'm using gcc 11.4.  Is
that
just too old?
