Intermittent args-out-of-range error

[jamescherti]

An intermittent args-out-of-range error occurs during Jinx idle checking when re-search-forward is invoked. The error originates from jinx--check-region, called via jinx--timer-handler:

Debugger entered--Lisp error: (args-out-of-range 52885 52885)
  re-search-forward("\\<\\w+\\>" 64025 t)
  jinx--check-region(52821 64003 nil)
  jinx--check-pending(44908 78227)
  jinx--timer-handler()
  apply(jinx--timer-handler nil)
  timer-event-handler([t 0 0 200000 nil nil nil idle 0 nil])

This is hard to diagnose without a minimal recipe. I've never observed such a problem, so it might be related to another package or to some Emacs problem. I'll see if I can add a workaround, but it would be better to understand what is causing this.

The odd thing here is also that re-search-forward is called with the argument NOERROR=t, so it must not error. I cannot reproduce the error for example when executing this code:

(re-search-forward "foo" 9999999 t)

Hello Daniel,

Thank you for taking a look. I tried reproducing the issue reliably using a few different scenarios, but I have been unable to reproduce it.

I will close the discussion for now, and I will reopen it if I manage to isolate a clean way to reproduce the problem.
