Timers are run in a rather unpredictable context, so you'll want to do
something like:

    (add-hook 'prog-mode-hook
              (lambda ()
                (run-with-idle-timer 1 nil
                  (lambda (buf) (with-current-buffer buf (flycheck-mode 1)))
                  (current-buffer))))
