It also does not work on Forth systems where the xt is not usable as a
return address, among them most systems based on threaded code, e.g.,
Gforth, even if the systems don't perform inlining or tail-call
optimization.

No, that's an unreliable technique even on systems where it works,
because it does not catch exceptions.

The way to perform cleanup actions is to wrap the protected code with
CATCH, then perform the cleanup, then THROW any exception onward.  E.g.:

: hex.-helper ( u -- )
  hex u. ;

: hex. ( u -- )
  base @ >r
  ['] hex.-helper catch
  r> base ! throw ;

A portable technique is to redefine ";":

: ; POSTPONE predefined-set-of-actions POSTPONE ; ; immediate
