The following code snippet also causes an ICE (g++43 (GCC) 4.3.0 20070828
(experimental) with -Wall, -g and -std=c++0x)
test4.cpp: In instantiation of A<int>:
test4.cpp:11: instantiated from here
test4.cpp:7: internal compiler error: tree check: expected tree_vec, have
type_pack_expansion in tsubst_copy_and_build, at cp/pt.c:10434
#include <type_traits>
template <typename... T>
struct A {
template <typename... U>
typename std::enable_if<(sizeof...(T) == sizeof...(U)),A&>::type
operator=(A<U...> const&) {}
};
int main() {
A<int> a;
A<int,double> b;
a = b;
}
