--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- You need to use std::ranges::advance here, because iota_view is "special". The reason std::advance doesn't work is that the type of v.begin() does not meet the Cpp17InputIterator requirements, because its difference_type is __int128, which is not a signed integer type when using -std=c++17 (but it is when using -std=gnu++20). Failing to meet the Cpp17InputIterator requirements means that std::iterator_traits<decltype(b)>::iterator_category defaults to output_iterator_tag. And you can't advance an output iterator.
