I can reproduce it on Ubuntu Karmic; with the following package
versions:

$ dpkg-query -W expect tcllib tcl bash dejagnu
bash	4.0-5ubuntu2
dejagnu	1.4.4.git20080407-1
expect	5.43.0-17
tcl	8.4.16-2
tcllib	1.11.1-dfsg-2

It seems that this is really a failure in test code. The expect call in
test/unit/compgen.exp doesn't swallow the prompt, then sync_after_int
swallows then earlier prompt and so on. Perhaps this problem is only
revealed by certain versions of expect? I didn't take a very close look.
