Thanks.

Maybe the documentation 
(http://www.freepascal.org/docs-html/ref/refsu50.html#x126-13300011.4.4) 
can be modified to clarify this since the statement:

"A constant argument is passed by reference if its size is larger than a 
pointer."

leads to the conclusion that double types (8 bytes) would be passed as 
reference in 32bit code.
