### Reproduction
`-target x86_64-windows -std=c++23`
```
struct TestStruct {
};
template <auto memberPointer>
struct TestTemplate {
constexpr static int constexprStaticValue = 0;
template <int>
struct InnerStruct {
};
using InnerType = InnerStruct<constexprStaticValue>;
};
struct TestRecursive {
TestStruct link;
TestTemplate<&TestRecursive::link> tree;
};
void TestFrame() {
TestRecursive Test;
}
```
### Warning
```
<source>:24:6: error: stack frame size (118115794992) exceeds limit (4294967295) in 'void __cdecl TestFrame(void)' [-Werror,-Wframe-larger-than
```
The same code works when targeting macOS or Linux.

A workaround is to replace the `constexpr static` with an `enum`.
