Yup; with that patch applied, the bus error goes away.

But it's an odd problem -- I've tried building on three machines now,
and it only fails on one.  The machine it fails on and one it works on
are both Debian bullseye, both with the same compiler version, etc.  And
on the one machine it does fail on, it only fails when saying "make -j2"
or higher.

So for all I know, there is some kind of very strange hardware error on
that machine...  although that's looking kinda unlikely now.
