Actually, the problem is known (see http://www.freepascal.org/mantis/view.php?id=7338 or bottom of http://www.freepascal.org/wiki/index.php/Issues_2. 0.4) and not really specific to just one unit (although unit Graph is known to be affected). I guess that it might be useful to have a look at register allocation and stack changes, but I didn't manage to find time for doing it yet. :-( Tomas _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
