I see no difference between length dynamic array property and your "lower 64 bits of value" (also between ptr and "higher 64 bits of value"). And passing a pointer to dynamic array is not the same thing as passing pointer to the first element: http://dpaste.dzfl.pl/8f91aed8 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
