Sometimes a race condition is in just two lines of code

A race condition can be this small: if Assigned(Setting.OnChanged) then Setting.OnChanged(Setting); If in between these lines, the value of Setting.OnChanged*becomes nil, then you have an access violation. It is a very slim, but real chance. –jeroen
