Yes, this appears to be a mount problem that affects many programs, not a coreutils problem per se.
The discrepancy that you observed between "mv" and "du" could be explained by the fact that "mv a/b c/d" changes C and also looks at A's and C's device number, whereas "du a/b c/d" needs to look only at A/B's and C/D's device number. So I don't see a bug. And anyway, the mount is the real problem here.
