I haven't debugged it properly either, but the fix suggested in
#559392 of adding this to src/s/gnu-kfreebsd.h works:
#define BROKEN_FIONREAD
That disables code paths like these in keyboard.c:
/* Determine how many characters we should *try* to read. */
#ifdef FIONREAD
/* Find out how much input is available. */
if (ioctl (fileno (tty->input), FIONREAD, &n_to_read) < 0)
And in sysdep.c:
#ifdef FIONREAD
status = ioctl (fd, FIONREAD, &avail);
#else /* no FIONREAD */
/* Hoping it will return -1 if nothing
available
or 0 if all 0 chars requested are read. */
if (proc_buffered_char[fd] >= 0)
avail = 1;
else
{
avail = read (fd, &buf, 1);
if (avail > 0)
proc_buffered_char[fd] = buf;
}
#endif /* no FIONREAD */
So perhaps it's some glibc or kernel bug related to ioctl()? This
issue is most likely not specific to Emacs.
Has anyone contacted upstream about this bug?
Here's some unrelated issues that I've run into with thu kFreeBSD port
thus far that I haven't found bugs for:
* The debian-installer doesn't ask for a keyboard layout.
* Almost no docs, for solving e.g. that issue. I only found out about
/etc/kbdcontrol.conf by asking around on IRC. This is to be
expected, but presumably needs to be fixed before it can go into
stable.
