Bug ID: 70648
Summary: [6 Regression] adplug-xmms fails to compile
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
CC: jason at gcc dot gnu.org
Target Milestone: ---
template <class T, class V> struct C
{
template <class... U>
constexpr C (...) : c { static_cast<U &&>(0)... } {}
constexpr const V &operator[](T) { return c[0]; }
V c[T::F];
};
enum D { E, F };
struct A
{
struct G
{
typedef int *H;
int g, h;
C<D, H> i;
constexpr G () : g (), h (), i{} {}
constexpr G foo (H) { return G (0, 0, 0, 0, i[E]); }
constexpr G (int, int, H, H, H) : g (), h (), i{} {}
};
};
struct B : A
{
static constexpr auto b = G ().foo (0);
};
fails to compile with -std=c++11, starting with r234013. No idea whether the
error is valid or not, and perhaps the reduced testcase also doesn't exactly
match the original, I've been reducing on accepted by r234009, rejected by
r234013.
