Also,to add to what I posted originally, `toggle-debug-on-error` does not
help  in this case as all I get in the *Backtrace* is:

Debugger entered--Lisp error: (args-out-of-range 1519)

Here's some new info:
- The Args out of range error seems to appear randomly.. I repeated doing
`C-h v save-place-mode`. At times the errors happened and at times it
didn;t.
- Also the integer in the argument to `args-out-of-range` showed up to be
different every time the error happened on doing C-h v on the same variable.

And "(setq debug-on-message "Args out of range")" does not trigger the
debug.
Is that because that message is printed by a C function?
