Does this still fail?  I've done a non-LTO profiledbootstrap on aarch64 as well
as
LTO profiledbootstrap on aarch64 recently:

https://kojipkgs.fedoraproject.org//work/tasks/5554/109705554/build.log

Still happens but bisecting it has proven unreliable. I'm going to call this
WAITING until I get a chance to at least give some standalone build command
which fails.
