Note, the functionality being tested is still guarded by the unstable compiler option `-Z saturating-float-casts`, so there's no user impact here yet. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below.
