--- Comment #6 from cqwrteur <unlvsur at live dot com> --- Your argument is not correct when you can just detect all the iterator methods are noexcept. Plus, the standard does not need you to handle exceptions if iterator throw it but to terminate. Btw what is the point of contiguous_iterator if i am not allowed to use std::to_address to optimize code? The whole point of contiguous_iterator is that i am allowed to use pointer arithematics directly.

Performing the algo on raw pointers would alter the behaviour. -- You are receiving this mail because: You are on the CC list for the bug. You reported the bug.
