PR27853, Infinite loop in dwarf.c
Not quite infinite but much longer than it need be. The problem is
triggered by read_and_display_attr_value incrementing "data" past
"end". read_and_display_attr_value shouldn't do that, but be
defensive.
PR 27853
* dwarf.c (display_formatted_table): Test for data >= end rather
than data == end.
(process_extended_line_op): Likewise.
(display_debug_lines_raw): Likewise.
(display_debug_lines_decoded): Likewise.
