    $2 = (struct Lisp_String *) 0x23c9d20
    "No further undo information"
    (gdb) p *$
    $3 = {
      size = 27,
      size_byte = -1,
      intervals = 0x0,
      data = 0x243d8ac "No further undo information"
    }

It looks valid to me.
So what directly caused strout to crash?
Please investigate its code and its data
and figure  out the immediate cause of the crash.

    I don't know how INTERNAL_CONDITION_CASE is invoked here,
    is it invoked by jumping?

It is invoked from its caller in keyboard.c,
but errors return to it with longjmp.
longjmp could be how control got to it this time.
