COMMAND

    xterm(1)

SYSTEMS AFFECTED

    X11R5

PROBLEM

    There is an escape sequence  which will crash xterms. Try  setting
    the font  to one  that's only  1 point  high (it  doesn't have  to
    exist, but make sure it doesn't match a scaleable font) --  xtattr
    will generate this.  Xterm will dump  core and exit.  It will even
    pass through mail.
