Patch looks sane to me.

It is relatively easy to run 32 bit containers on a 64bit host, that’s what the Debian CI environment that hit this is doing.

I think the bigger question here is fuzzing on 32 bit right? That likely would have caught this quickly.

I don’t know…roughly though it feels to me as long as the Linux kernel supports 32 bit we are going to keep getting pulled to do so too. Especially there’s a long tail of 32 bit ARM out there as I understand it.
