bug#12745: crash in bidi_pop_it during (idle) redisplay

[Ami Fischman]

Is it correct that the character at buffer position 1295 is a newline?

Yes.

 

Also, what are the values of the following?
  it->stack[0].current

 

(gdb) p  it->stack[0].current

$63 = {

  pos = {

    charpos = 1295, 

    bytepos = 1295

  }, 

  overlay_string_index = 0, 

  string_pos = {

    charpos = -1, 

    bytepos = -1

  }, 

  dpvec_index = -1

}

>   it->stack[0].string

 (gdb) p   it->stack[0].string

$66 = 9755602

(gdb) xtype

Lisp_Symbol

(gdb) xsymbol  it->stack[0].string

$67 = (struct Lisp_Symbol *) 0x94dbd0

  "nil"

>   it->stack[0].method

(gdb) p   it->stack[0].method

$68 = GET_FROM_BUFFER

 

>   it->method

(gdb) p it->method

$69 = GET_FROM_BUFFER
