--- Comment #4 from gcc-bugs at marehr dot dialup.fu-berlin.de ---
I (may) have run into the same issue:

```
template <typename value_t>
struct twice
{
    value_t _first{};
    value_t _second{_first};

    struct inner{};

    inner get() const
    {
        return inner{};
    }
};

template<typename value_t>
twice(value_t first)
  -> twice<value_t>;

int main()
{
    auto result = twice{0u}.get();
}
```
