--- Comment #3 from Jack Howarth <howarth.at.gcc at gmail dot com> --- (In reply to Jonathan Wakely from comment #2) > This is user error, std::search() requires forward iterators and the library > is not required to diagnose it. Defining _GLIBCXX_CONCEPT_CHECKS causes it > to be rejected. Is the use of _GLIBCXX_CONCEPT_CHECKS well enough advertised in the documentation that we can expect the average developer to know to invoke it?
