Emacs shouldn't crash while reading data it has been able to write (well, at least I would expect it).
Could it be that the syntax-table structure has been changed recently in a way that makes it impossible 
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 
(read (current_buffer)) 
on a buffer containing the undo-tree history (part of which is in the previous mail).
The point needs to be at the beginning of the [cl-struct-undo-tree .
