Requirements of irrelevant > overloads should not be considered, as it can potentially lead to falsely > reporting a cyclic dependency. This is as specified by http://wg21.link/cwg2369 I think it would be reasonable to allow a compiler to accept the testcase under a generalization of 13.9.1/9: "If the function selected by overload resolution (12.4) can be determined without instantiating a class template definition, it is unspecified whether that instantiation actually takes place." But that does not require a compiler to accept it. It might make sense to check non-dependent conversions that don't require template instantiation, then constraints, then non-dependent conversions that do require template instantiation. But that's a matter for the committee; G++ is conforming to the current working paper.

Right.

Yes. Perhaps PR81359 or PR88368, or both, were wrongly resolved.
We cannot correctly resolve is_nothrow_constructible until we've parsed the
DMI. Given that, we have three options:
1) Conservatively say no.
2) Optimistically guess yes.
3) Non-SFINAE error.
PR81359 changed our behavior from 3 to 1.
#2 seems the clear worst choice, as it can lead to things unexpectedly
throwing.
#3 means people have to jump through hoops to make their code compile.
#1 means silently pessimized code for anything that relies on
std::is_nothrow_constructible in the rest of the translation, since the
value is permanently cached.
If we choose #1, we have another choice for is_constructible: should it be
true (giving A() a throwing exception-spec) or false?
PR88368 changed our choice from true to false.
Any opinions on what our behavior should be? Should there be an LWG issue?
This is related to CWG1890, and the general issue that we don't currently parse
on demand like we do instantiate on demand for templates.
So one workaround is to wrap DataWith* in a dummy template:
#include
using namespace std;
template
struct DataWithStruct {
struct A {
int number = 5;
};
/*typename*/ is_nothrow_constructible::type t = true_type{};
};
DataWithStruct<> d; // OK
or move the nested class out so we can finish parsing it before the use:
#include
void testVarStruct()
{
struct A {
int number = 5;
};
struct B {
bool flag = false;
};
struct DataWithStruct {
using Member = std::variant;
Member data;
};
auto d = DataWithStruct{};
}
