Summary: [C++0x] Segmentation fault with list-initialization,
void initializers and variadics
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: daniel.kruegler@googlemail.com
CC: jason@redhat.com
The following code causes a segmentation fault with 4.7.0 20110422
(experimental) in C++0x mode at the line marked with #:
//--------------
template<class T>
struct add_rval_ref {
typedef T&& type;
};
template<>
struct add_rval_ref<void> {
typedef void type;
};
template<class T>
typename add_rval_ref<T>::type create();
template<class T, class... Args>
decltype(T{create<Args>()...}, char()) f(int);
template<class, class...>
char (&f(...))[2];
static_assert(sizeof(f<int, void>(0)) != 1, "Error"); // #
//--------------
"internal compiler error: Segmentation fault"
The code should be accepted.
