    Ok.  You must have hit '^T'.  There are known bugs in ^T, in FreeBSD
    and in DragonFly.

    In this case it looks like ttyinfo is trying to dereference p_wmesg
    which is actually p_thread->td_wmesg, just after the thread has been
    detached.

    I will commit a fix for this particular issue, thanks for your bug
    report!
