Bug ID: 61791
Summary: [C++11] [constexpr] Additional overloads of std::real
should be a constexpr function
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: kariya_mitsuru at hotmail dot com
I think that the sample code below should be compiled successfully.
===========================================
#include <complex>
static constexpr double d = std::real(10);
int main() {}
===========================================
Note that it is compiled successfully if the argument is
std::complex<double>(10) instead of 10.
According to C++11 standard 26.4.9[cmplx.over] paragraph 2, "if either argument
has type complex<double>, double, or an integer type, then both arguments are
effectively cast to complex<double>."
Therefore, I think it should be compiled successfully too.

Sorry, the text which should be quoted was mistaken.
