One user reported that latest FPC fails to compile a recent Lazarus: http://bugs.freepascal.org/view.php?id=22029

The bug was assigned to me, but I can't do much about it except to commit some workaround. And I am now away (at ACM ICPC World Finals), so it will take more than a week till my return.

Can some FPC developer please look into the issue?
