Run `trap' after logging in with bash as your login shell.  If it
reports SIGINT as ignored or trapped and running a strange-looking
command, look at /etc/profile.  Chances are good it contains
something like `trap 2 3', which is deprecated syntax and ends up
running the command `2' when signal 3 is received.

If this is the problem, apply the patches to bash-3.0.  One of them
(patch 3) addresses this issue by restoring some backwards
compatibility to `trap'.
