Yes:

1. Install Octave.
2. emacs -Q
3. M-x run-octave
4. Switch to octave-mode in the scratch, delete everything.
5. Type 'abs ', wait. See that message.

I don't see any freezing, though.

Only see this message once (repeated twice, though) in an 'emacs -Q' 
session, but in my normal session I can repeat it at will by deleting 's 
' and typing them again.

Indeed, but what foreground code? The major mode is octave-mode.
