g++ -v

The sample code below should be compiled successfully but gcc 5.0 rejects it.

================= sample code =================
constexpr int i1 = 1;
constexpr int i2 = 2;

constexpr auto b = &i1 == &i2;

int main() {}
================= sample code =================

Note that gcc 4.9.2 accepts it.
