Can you provide some additional info:

p frame_title_ptr
p frame_title_buf
p frame_title_buf_end
pp mode_line_string_list


I suspect that frame_title_ptr somehow got cleared, but I don't see how
it happened.

Can you rerun emacs with the following patch installed, to see if it catches
the error earlier.

Thanks.
