I'm not sure that it does matter, I was surmising. The problem with the
SPECL_INDEX imbalance arose because Emacs got back to Fbyte_code and checked
for an imbalance before reaching a call to unbind_to from Fsignal (from QUIT in
Ffuncall). However Fsignal also appears to clean up a lot of other things.
Maybe some of these could cause a problem just as the binding imbalance did.
