Thanks!
I’ve narrowed the problem further to [firstRectForCharRange]. Some calls never return. Activating an input method makes Emacs issue excessive calls to this method. Specifically, the following code gets stuck somewhere.
if (WINDOWP (echo_area_window) && ! NILP (call0 (intern ("ns-in-echo-area"))))
win = XWINDOW (echo_area_window);
else
win = XWINDOW (FRAME_SELECTED_WINDOW (emacsframe));
