And while normally calling convention-related stuff would almost never change because it would break all interfacing with dynamic libraries compiled by previous FPC versions, in practice such FPC-compiled libraries are (fortunately) not in widespread distribution or use and hence we can still fix such bugs.</div><div><br></div><div>External review or rigorous testing of the calling convention code in all possible scenarios could also help with getting everything fixed in one release, instead of piecemeal one change at a time.</div><div><br></div><div><br></div><div>Jonas</div></body></html>
