This is because stdout and stderr are mixed:

musl seems to behave like the patch below, while glibc always prints 
the "wrong" order.

Not sure whether we should really use fflush() to define the order of 
error and non-error messages. We could also simply "fix" the the test 
script by not using "--verbose". or by using "stdbuf -o0 -e0 
rename ..."
