Error message with Visual Studio 2017
#include <complex>
// clang crashes here with any array size > 1
std::complex<double> v[2];
// I suppose the reason is a constexpr constructor with the parameter type
being const &. Please see the following explanation and the attachment
struct A
{
constexpr A(const int & = 0) {}
};
struct B // = A without &
{
constexpr B(const int /*&*/ = 0) {}
};
struct C // = A without constexpr
{
/*constexpr*/ C(const int & = 0) {}
};
A a1[1]; // OK
A a2[2]; // clang crashes
B b[2]; // OK
C c[2]; // OK</pre>
