"illegal hardware instruction (core dumped)" cvsup/amd64

Hello,

Since upgrading my world with a -current built last night, cvsup
dumps core on me. Any idea?

It is a Intel/ATOM 330 box used in 64bit mode. Everything else on
the box runs fixe.

Recompiling cvsup + ezm3 didn't fix the problem; neither did trying
a libc from October.
