    Thank you, I hadn't thought that section of the manual relevant to me, but
    that makes it quite clear what the problem was. I take it I could also call
    fl_set_event_callback(do_nothing_function), and I would not have to worry
    about fl_do_forms() returning an FL_EVENT.

    I had registered event callbacks with fl_add_event_callback(), so that
    removing them from the queue with fl_XNextEvent() wasn't necessary. But, one
    of the events I registered was ConfigureNotify, and the mask that selects that
    event also selects other events like MapNotify, which I didn't have callbacks
    for. So, eventually, my application would crash for no apparent reason.
