Указатель на вариантный тип

Consider the following (simplified code):

 function CreateVariantPtr(_Value: variant): pVariant;
 begin
 GetMem(Result, SizeOf(Variant));
 Result^ := _Value;
 end;

Seems pretty simple, doesn''t it? Anybody who can spot the bug? I got spurious access violations in the line Result^ := _Value; Ok, the reason: Memory allocated with GetMem is not initialised, so the "Variant" pointed to by Result contains some random data, for example something that might represent a variant type which requires some finalisation when the variant is changed, lets say a variant array of some sort. But this finalisation won''t work because the content is just some random garbage, and sometimes I was lucky (I mean that!) and got an access violation that allowed me to spot the error. The fix:

 function CreateVariantPtr(_Value: variant): pVariant;
 begin
 GetMem(Result, SizeOf(Variant));
 Initialize(Result^);
 Result^ := _Value;
 end;
