Hello, FPC developers' list.

What should MemSize function do? Should it return the same info for statically allocated memory?

I don't see any documentation on MemSize function here: http://freepascal.org/docs-html/rtl/system/memoryfunctions.html

So I decided to test it since we rely on it in LCL:

var
   Data: array[0..2] of Integer;
begin
   WriteLn(MemSize(@Data[0]));
end.

Without heaptrc on 32bit windows:
4294967284
With heaptrc:
0

For statically allocated memory it will work just as badly as freemem and reallocmem.
