--- Comment #6 from Iain Buclaw <ibuclaw at gdcproject.org> ---
I just encountered this when reviewing some @safe code in the dmd compiler
implementation.


The crux of which boils down to:
```
int findCondition() @system;

int parseGeneric(int param = findCondition()) @safe
{
    return param;
}

int parseSpec() @safe
{
    return parseGeneric(); // Compiles!
}
```

Call the function directly in @safe code, and you get the expected error.
