C++23 std::string_view added a range constructor that is constrained with a concept check that in particular checks if the range is contiguous. In that check, the range iterator type is checked. Since fs::path members now test whether the source argument is convertible to std::string_view, that concept check is performed whenever the overload resolution or SFINAE check is performed. This caused a problem if the check was performed before fs::path::iterator is defined, since the result of the check formally changes when the iterator gets defined. To work around this, move any fs::path non-template member functions that call to other members (including constructors) which may involve overload resolution or SFINAE checks that might require testing whether std::string_view is constructible from fs::path out of fs::path definition and past the fs::path::iterator definition. This was also reported to gcc team: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106808
