Bug 17368 – [DIP1000] scope T** implicit convertion to scope T* allow to escape pointer

Code below: ``` void main () @safe { getPtr(); } void getPtr () @safe { int* ptr2; bar(&ptr2); assert(ptr2 !is null, "Oops, I have a pointer to bar.value"); } void bar (scope int** ptr2) @safe { int value; foo(ptr2, &value); } // Needs to be 'return scope' so that the compiler believes 'ptr1' has longer lifetime thatn 'ptr2' void foo (scope int** ptr2, scope int* ptr1) @safe { foobar(*ptr2, ptr1); } int* foobar (scope int* p1, return scope int* p2) @safe { p1 = p2; return p2; } ```

My bad, this example is totally wrong.
