Bug ID: 94302
Summary: Implement DR 2310: Type completeness and
derived-to-base pointer conversions
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
This issue was approved as a DR at Kona 2019:
template<typename A, typename B> struct check_derived_from {
static A a;
static constexpr B *p = &a;
};
struct W {};
struct X {};
struct Y {};
struct Z : W,
X, check_derived_from<Z, X>, // #1
check_derived_from<Z, Y>, Y { // #2
check_derived_from<Z, W> cdf; // #3
};
All three attempted conversions in the example are ill-formed.
