Any variable initialized as `static constexpr` variable inside `consteval` is not keeping its value in runtime:
```c++
consteval const int & get_value() {
constexpr static int value = 42;
return value;
}
int foo() {
return get_value();
}
```
generates assembly (with clang 18.1):
```asm
foo(): # @foo()
push rbp
mov rbp, rsp
mov eax, dword ptr [rip + get_value()::value]
pop rbp
ret
get_value()::value:
.long 0
```
confirmed with clang 16+ to current `main` branch (`597ac471cc7da97ccf957362a7e9f7a52d6910ee` at compiler explorer)

same thing happens to strings and arrays ... their storage is all zeros
