Re: My Emacs unicode 2 crash again when I do some *Replace String (M-%)*, I give the debug informations under gdb in the attachments.

By the way,

It shows this info:

Breakpoint 1, abort () at emacs.c:431
431       kill (getpid (), SIGABRT);
(gdb) bt full
#0  abort () at emacs.c:431
No locals.
#1  0x08085a09 in try_window_id (w=0x8b927f0) at xdisp.c:15191

The function try_window_id has this code:

try_window_id (w)
     struct window *w;
{
[...]
  /* Update window_end_pos and window_end_vpos.  */
  if (first_unchanged_at_end_row
      && !last_text_row_at_end)
[...]
  else if (last_text_row_at_end)
[...]
  else if (last_text_row)
[...]
  else if (first_unchanged_at_end_row == NULL
           && last_text_row == NULL
           && last_text_row_at_end == NULL)
[...]
  else
    abort ();   <-- line 15191
[...]
}

So it's impossible to reach the line 15191 with any
combination of values of these three variables:

  first_unchanged_at_end_vpos
  last_text_row
  last_text_row_at_end

Is it GCC bug?  Which version of GCC have you used?
