I recently upgraded Slime, and now I keep getting these very annoying warnings, usually when I do something in the modeline, but also at other apparently random times:

(1) (error/warning) Error in `post-command-hook' (setting hook to nil): (wrong-type-argument natnump t)

I've seen this, too. Has this been addressed since by Raymond?

If I turn debug on, this is what I get:

Debugger entered--Lisp error: (wrong-type-argument natnump t) signal(wrong-type-argument (natnump t)) set-itimer-restart(("run-with-idle-timer<2>" 0.2 0.2 eldoc-print-current-symbol-info t t nil (19018 24548 646301)) t) timer-set-idle-time(("run-with-idle-timer<2>" 0.2 0.2 eldoc-print-current-symbol-info t t nil (19018 24548 646301)) 0.2 t) eldoc-schedule-timer()

Uhm, why does the warning seem to come from eldoc?

I also observed the problem that was reported here earlier:

slime-bug("Caught error during fontification while searching for forms that are suppressed by reader-conditionals. The error was: (cl-assertion-failed (<= (point) limit))

but I was able to stop XEmacs doing whatever it was doing with C-g before it ran out of memory.

Yes, that's the same issue as Raymond's. For the time being, do not use the slime-fontifying-fu contrib with XEmacs. Either do not load it, or (if you use slime-fancy which automatically includes it) place

(setq slime-highlight-suppressed-forms nil)

into your ~/.emacs.
