"...cannot be interpreted at compile time" I can't find the source of the error!

With no extra arguments I get a "compile time context created 
here" addendum. Does that not show up for you or does the line 
not make sense still?

It might also be new. This is with v2.097.1

```
example.d(6): Error: `atoi` cannot be interpreted at compile 
time, because it has no available source code
example.d(12):        compile time context created here
example.d(13): Error: no property `val` for type `void`
```

 From this code:

```d
extern (C) int atoi(const(char)* nptr);

class N {
     int val;
     this() {
         val = atoi("2");
     }
}

void main() {
     import std.stdio : writeln;
     enum n = new N(); // line 12
     writeln(n.val);
}
```
