Thanks.

This is an entirely different place and condition:

  #1  0x00000001005b9a67 in die (msg=0x100a51d98 <DEFAULT_REHASH_SIZE+8416> 
"!it->bidi_p || (EQ (it->bidi_it.string.lstring, Qnil) && it->bidi_it.string.s 
== NULL)", file=0x100a4fcc0 <DEFAULT_REHASH_SIZE+8> "xdisp.c", line=8222)
      at alloc.c:7160
  No locals.
  #2  0x00000001004435aa in next_element_from_buffer (it=0x2269b0) at 
xdisp.c:8220
          success_p = true

And it again is a bogus assertion violation: as you see in frame #5,

            string = {
              lstring = 4306669618, 
              s = 0x0, 

(4306669618 is nil), the condition of the assertion does in fact hold.
