Dunno whether that helps. This happens in display_line in the line marked below: row->truncated_on_right_p = 1; it->continuation_lines_width = 0; reseat_at_next_visible_line_start (it, 0); row->ends_at_zv_p = FETCH_BYTE (IT_BYTEPOS (*it) - 1) != '\n'; <<<<<< break; } A SIGSEGV there doesn't make much sense, but I added something in emacs-24 revision 117374 to plumb the only possibility I could think of.
