Whoa!  We had that check there for 9 years, and it was introduced to
avoid crashes (see bug#23869), so removing it now, during a pretest,
is scary.  Frankly, I'd rather revert the offending change which
caused the regression and let Emacs 30 live with bug#65451, which it
was supposed to fix.

And I don't think I understand how a single line you moved in
63588775fcb could cause this check to signal an error in the scenario
of this bug.  Can you explain?
