And I reproduced your result with emasc -Q.
I'm puzzled as to how something in my setup could be making it
uninterruptible, but clearly it's not an Emacs bug; do please close
this, and sorry for the noise: I should have thought of an emacs -Q
test before writing the original report.
If I run smie-config-guess manually with my setup, then I can
interrupt it. The problem arose when I ran it as part of
dtrt-indent-mode (3rd-party code that I maintain):

But now I can't reproduce the problem, whereas I could several times
earlier today. Oh well. Sorry again.
