     That's not a big issue. The constructor taking a rvalue reference 
and an allocator doesn't take care about safe iterators. They should be 
swap like in the move constructor when allocator is equivalent and 
invalidated if we have not been able to move memory. I plan to submit a 
patch to fix all implementations the same way at once but I can include 
it in this patch if you prefer.
