Summary: ICE in make_dependency, at cp/module.cc:14467
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
Hello
I believe it's a recent regression (didn't notice it last weekend).
``` M.cpp
export module M;
import std;
export
template<int d>
class T
{
private:
class Helper
{
public:
std::vector<int> PtoVec(std::span<std::size_t const> const Tag) const
{
return Tag | std::views::transform([this](auto Tag) { return
T<d>::Punto(Tag); })
| std::ranges::to<std::vector>();
}
};
private:
static inline std::vector<int> PuntoVec;
public:
static int Punto(std::size_t const i)
{ return PuntoVec[i]; }
};
```
