I agree that it should be anchored. In practice given the filenames
involved it doesn't make a difference.

I don't agree with that part. The fact that the file is diverted doesn't
change the issue. If ld.so is not in sync with libc.so you should expect
a crash. If ld.so is diverted, only libc.so will be unpack and the crash
will happen.
