The call chain looks like this:

process_full_comp_unit
-> process_die
-> read_file_scope
-> handle_DW_AT_stmt_list
-> dwarf_decode_lines
-> psymtab_include_file_name

What happened formerly is that process_full_comp_unit installed an outer
cleanup, and then psymtab_include_file_name took advantage of that by
leaving some dangling cleanups.
