Hmmm, I see a couple buildfarm animals are upset about the minmax-multi
patch. It does pass for me both on x86_64 and 32-bit ARM (rpi4), so I'm
unable to reproduce this. But most of the machines having issues seem to
be sparc variants, and snapper does this:


[New LWP 1471]

I recall seeing "bus error" on sparc with other patches because of
alignment issues, so I wonder if this is what's happening here.
