I have been building Emacs regularly from the master branch.
In the last 2-3 days, this new error starts popping up frequently.
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
timer-next-integral-multiple-of-time((63065 20560) 60)
timer-event-handler([t 23440 6080 0 60 display-time-event-handler nil nil 0])
timer-next-integral-multiple-of-time accepts TIME and SECS (integer) as arguments, and the values (63065 20560) and 60 seem fine (or not?).
Before I dig deeper into debugging if some package went rogue, do you think this number-or-marker-p error is related to bignump changes under the hood?
