<pre>The following snippet seems to produce contradictory results when comparing
const char* pointers in a constexpr expression:
constexpr auto name1() {
return "test1";
}
constexpr auto name2() {
return "test2";
}
int main() {
constexpr auto b1 = (name1() == name1()); // compiles cleanly
constexpr auto b2 = (name1() == name2()); // doesn't compile
}
Apparently (<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86369">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86369</a>), neither should
compile. Live code here: <a href="https://godbolt.org/g/8W4VrS">https://godbolt.org/g/8W4VrS</a></pre>
