re PR middle-end/71907 (missing buffer overflow warnings with -flto)
2016-07-19 Richard Biener <rguenther@suse.de>
PR lto/71907
* lto-streamer-out.c (DFS::DFS_write_tree_body): For blocks
with an abstract origin that is not an inlined function outer
scope add a self-reference as abstract origin.
* tree-streamer-out.c (write_ts_block_tree_pointers): Likewise.
