Bug ID: 100606 Summary: Please complete LWG3490: ranges::drop_while_view::begin() is missing a precondition. Product: gcc Version: 12.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: hewillk at gmail dot com Target Milestone: --- Hi, libstdc++ has not yet completed LWG3490 which is very simple and only needs to add an assertion. Since msvc-STL has added it (https://github.com/microsoft/STL/blob/main/stl/inc/ranges#L2529) and it also appears in the latest [range.drop.while#view-3], I think it is appropriate to complete it now. thanks.
