http://stackoverflow.com/questions/17951412/what-does-the-default-tarray-sort-comparator-actually-do-and-when-would-you-use Thank you for the link, because now I know what was *really* bugging me about the code all the time (you know that feeling that you instinctively know that something is wrong, but you can't really pinpoint.it? ;) ). The point is that it is not necessarily guaranteed on each and every platform that the parameter passing of a (interface) method is the same as for a global function with an additional instance parameter. This *might* be true for those platforms on which Windows runs and thus we need to correctly support COM interfaces, but on other platforms this *could* be completely different (e.g. a platform could pass the instance in a register instead of the stack while normal functions get all their parameters from the stack; this would totally mess up the parameters that the functions expects). And *this* is something I don't want to deal with as this could potentially break every time we improve or fix something in the parameter passing code and then only for specific platforms... So if you would instead change the code to use real class instances that implement the interfaces (they can be lazily allocated singletons or so) then I'd definitely be inclined to include the code in trunk.
Thanks Sven, I am glad there is a solution, I was afraid there would not be one, and then we'd be caught in some kind of stalemate :-) Michael. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
