And I have reproduced it on amd64.  When I looked at the autoconf tests
that failed, they had clearly been corrupted in memory.  This is why I
don't use tmpfs on any of my systems: I may only _notice immediately_ when
data corruption causes autoconf to fail, but that doesn't mean that other
data isn't being corrupted!

Not good.
