Subject: [Bug libstdc++/52745] GCC4.7 vector uses copy instead of move constructor
Date: Tue, 27 Mar 2012 23:26:00 -0000	[thread overview]

Otherwise, if the move constructor by chance throws, the push_back cannot have
no effects, as required by 23.2.1/10. Actually the requirement holds for all
the containers, but only std::vector implements it in 4.7, the other containers
(I *think* only std::deque needs work) will follow.
