I have the following code that gets compiled with clang and runs correctly:
`include/based/template.hpp`
```c++
#pragma once
namespace based
{
template<typename... F>
struct overload : public F...
{
using F::operator()...;
};
template<typename... F>
overload(F&&...) -> overload<F...>;
} // namespace based
```
`example/template.cpp`
```c++
#include <iostream>
#include "based/template.hpp"
int main()
{
const auto l =
based::overload([](const int* i) { std::cout << "i=" << *i << '\n'; },
[](const double* d) { std::cout << "d=" << *d << '\n'; });
int i = 5;
l(&i);
double d = 7.3;
l(&d);
return 0;
}
```
but clang-tidy crashes with the following error:
```
