Thanks I was in the middle of debugging this.  I hit it with coreutils
`yes ""` on arm.

We've had these sorts of bugs in the past.  Wouldn't it be wise to push
out a new release?  Something like musl-  I can deal with
applying the patch but pushing out a another release signals to the
community that there is an update.  Just thought.
