***Generated by fuzzer.***
Clang trunk crashed and goes back to 19.1.
Compiler Explorer: https://godbolt.org/z/8fcesnhPs
Maybe related to #63242, but #63242 goes back to 17.0
## Program
```cpp
#include <functional>
auto recursiveLambda = [](auto, int n) {
struct S;
typeid(*static_cast<S *>(nullptr));
};
long result = recursiveLambda(recursiveLambda, 10);
```
## Stack Dump
```bash
