Bug ID: 94418 Summary: Please make reverse_iterator nothrow constructible when possible Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: rafael at espindo dot la Target Milestone: --- The standard in res.on.exception.handling says: An implementation may strengthen the exception specification for a non-virtual function by adding a non-throwing exception specification. So, as far as I understand, libstdc++ could make the constructors of std::reverse_iterator noexcept when the corresponding constructors of the underlying iterators are noexcept.
