I've reported the problem in the Debian BTS for dash:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=683671
Now I remember that the problem is described on:
http://www.cons.org/cracauer/sigint.html
And contrary to what I've said, zsh is also buggy, but only in the
case where the command is *not* the last one (I suppose that this
difference is because zsh does an exec for the last command, when
possible).

Actually, no. This was my test that was buggy:
ypig:~> cat trap.sh
#!/bin/bash
trap 'kill -INT $$' INT
sleep 3
ypig:~> zsh -c trap.sh; echo foo
^Czsh: exit 130 zsh -c trap.sh
foo
A correct test, with
trap 'trap - INT; kill -INT $$' INT
shows that "foo" is not output, as expected.
