           Summary: [DIP1000] Escaping scope pointers possible via struct
                    GC allocation
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: safe
          Severity: normal
          Priority: P1
         Component: dmd

The following compiles and runs with 2.074.0 and v2.075.0-devel-5cfc8d982
(latest master):

```
void main () @safe
{
    int* ptr = fwd();
    assert(ptr !is null);
}

int* fwd () @safe
{
    int i;
    return new Struct(&i).oops; // Leaving out `new` correctly detects escaping
}

struct Struct
{
    int* oops;
}
```
