Well, it's not as simple as a small C program, but this will do the
job on Debian testing (*):

The problem is that Tcl 8.4 is threaded, Expect isn't, and something
goes wrong when Expect gets loaded into Tcl.

(*) If no one uploads an updated Expect package anytime soon, the bad
    version is: 5.39.0-1
