 Following up on this: the t_line member of the struct tty that the
 ttyld_modem() macro is looking at (which should be an integer from 0
 upto but not including nlinesw, which is 9 on this system), is
 actually an address of some sort. The t_line integer's value is
 0xc5f0cd48. I have no idea how this could ever get there, I can't find
 anything in the kernel code that could cause this, at least, not by
 setting t_line itself. Perhaps the tty structure is corrupted by a
 function that is not supposed to do anything with t_line at all.
