Found yet another internal compiler error trying your code: https://bugs.freepascal.org/view.php?id=36388 The previous day was another internal compiler error with inline functions in case you missed it. ;) https://bugs.freepascal.org/view.php?id=36381 Regards, Ryan Joseph _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
