McKenney, Maged Michael, Jens Maurer, Peter Sewell, Hans Boehm, Hubert Tong, Niall Douglas, Thomas Rodgers, Will Deacon, Michael Wong, David Goldblatt, Kostya Serebryany, Anthony Williams, Tom Scogland, JF Bastien, Daniel Krügler, David Tenty Target Audience LEWG LWG Tracking issue View on GitHub Abstract The C++ standard currently specifies that all pointers to an object become invalid at the end of its lifetime [basic.life].
