--- Comment #3 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Creduce came up with:
markus@x4 tmp % cat Uni.ii
class A {
public:
int operator*();
};
template <typename T, typename Predicate>
void searchGen(int, int, T, Predicate p4) {
p4(0);
}
template <typename...> struct B;
template <typename MetaFunction, typename Type, typename... Types>
struct B<MetaFunction, Type, Types...> {
static void exec() { MetaFunction::template exec<Type>; }
};
template <typename MetaFunction, typename... Types> void forEachType() {
B<MetaFunction, Types...>::exec;
}
namespace {
struct C {
template <typename T> void exec() {
A __trans_tmp_1;
const auto target = *__trans_tmp_1;
searchGen(0, 0, 0, [=](T) { [=] { target; }; });
}
};
}
void ____C_A_T_C_H____T_E_S_T____75() { forEachType<C, int>; }
markus@x4 tmp % /usr/x86_64-pc-linux-gnu/gcc-bin/4.9.3/g++ -std=c++11 -c Uni.ii
markus@x4 tmp % g++ -c Uni.ii
Uni.ii: In lambda function:
Uni.ii:22:33: internal compiler error: in gimplify_var_or_parm_decl, at
gimplify.c:1776
searchGen(0, 0, 0, [=](T) { [=] { target; }; });
