Apparently this bug does not occur with v3.0.0-23-g7dc90a17e¹. It may
be that 00fbdfa7345765168e14438eed0b0b8c64c27ab9 reduces GC pressure,
which as a side effect makes the problem vanish.
It’s not satisfactory, but as a stop-gap measure, we could release 3.0.1
like this, which could make Guile 3 usable for Guix on AArch64.
Thoughts?

¹ Specifically, I tested by (1) building a tarball with “make dist”, (2)
running “guix build guile-next
--with-source=guile-next=the-tarball.tar.gz”, and (3) running that
Guile in the code above. For some reason, Guile 3.0.0 built “by hand”
would not reproduce the original bug, which is why I built it through
Guix.
