Bug ID: 91558 Summary: [C++11] <complex> should not be constexpr until C++14 Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: yichen.yan at inf dot ethz.ch Target Milestone: --- Detail: Constexpr for <complex> is in C++14 if I don't misunderstand. But a lot of testcases under libstdc++-v3/testsuite/26_numerics/complex/ (e.g. dr844.cc) runs with C++11 and check for constexpr (and pass). I haven't found some manual or doc explaining that, and wonder if this is a bug or some feature?
