Emacs shouldn't crash while reading data it has = been able to write (well, at least I would expect it).
Could it b= e that the syntax-table structure has been changed recently in a way that m= akes it impossible=C2=A0
to read one that has been printed with a= previous version of emacs?


I = should have said: in a previous _trunk_ version of emacs (couple of months)= .

To make it clear: I can reproduce the crash from= "emacs -Q" by evaluating=C2=A0
(read (current_buffer))= =C2=A0
on a buffer containing the undo-tree history (part of whic= h is in the previous mail).
The point needs to be at the beginnin= g of the [cl-struct-undo-tree .
