<pre>The following compiles with gcc but does not with clang:
template<typename T>
void construct() {
T(0);
}
template<typename T>
void tester() {
struct d {
void test() {
construct<d>();
}
constexpr d(T b) : a(b) {}
T a;
};
}
int main() {
tester<int>();
}

It fails with "fatal error: recursive template instantiation exceeded maximum
depth of 1024"</pre>
