The second example has an template missing but even adding that, the ICE is still there. ^ permalink raw reply [flat|nested] 2+ messages in thread

We even reject this and cause an ICE: ``` template<int = [](auto)constexpr{ return 0; }.operator()(1)> void f() { } ``` But those examples are all valid C++17 due to constexpr'ness. ^ permalink raw reply [flat|nested] 2+ messages in thread
