It shouldn't display that; there are different bugs in 3.0 and 3.1/3.2.

That's not right, either.

The correct output is "smith: 0.0". The `smith' from $dh, the literal
colon, the space from the spaces separating the "$@" (splitting on `:'
results in $1 being a null field), then the 0.0 ($2).
If you use nd="${dh}$*" before resetting IFS, you'll get the output you
in bash-3.0 through bash-4.0.
