```cpp
template <int N>
static constexpr void f() {
static_assert(N == 0);
}
void g() {
if constexpr (false) {
f<1>();
}
}
```
This fails to compile: https://gcc.godbolt.org/z/G87rsPjWo (GCC accepts)
Removing `constexpr` from `f()` makes this compile, but it shouldn't matter either way. `f()` is not odr-used, not constant-evaluated, or otherwise needs to be instantiated.
