Ok, it was my typo error! I mean 8-bytes boundary alignment,
of course.
So, for the structure

	type TPoint = record
        	       x,y: extended;

the function SizeOf(TPoint) reports 32 bytes in FPC, since in
Delphi it reports 24 bytes (with the same 8-bytes alignment).
It seems for me that we have an incompatible records alignment
between these compilers.
Am I correct here?
