[plt-scheme] Bug in write?

Hello,
In learning Scheme I found the following behaviour with DrScheme204 on Linux.
It seems that write has a bug (see the last vector #3(-14 2 ?)):

#3(#3(-6 4 2) #3(6 0 10) #3(-14 2 2))
; => #3(#3(-6 4 2) #3(6 0 10) #3(-14 2))  
(write #3(#3(-6 4 2) #3(6 0 10) #3(-14 2 2)))
; => #3(#3(-6 4 2) #3(6 0 10) #3(-14 2))
(newline)
(display #3(#3(-6 4 2) #3(6 0 10) #3(-14 2 2)))
; => #(#(-6 4 2) #(6 0 10) #(-14 2 2)) ; ok
