OK, I ran the failing test in GDB:

initmaster(int f UNUSED)
#ifndef VMS
# ifdef POSIX
    tcflush(f, TCIOFLUSH);
# else
#  ifdef TIOCFLUSH
    (void)ioctl(f, TIOCFLUSH, (char *) 0);
#  endif
# endif
# ifdef LOCKPTY
    (void)ioctl(f, TIOCEXCL, (char *) 0);
# endif

It's failing on an ioctl()

Not sure what to do next.
