Summary0036857: False duplicate identifier compiler error with private members in derived cladd
DescriptionA private member in a class will cause a compiler error to be displayed,
if there is a private member with the same name in some predecessor class.
Steps To Reproduce
 tCompilerBug = class( TCustomApplication)
    abc: String;
  procedure DoRun; override;

 tAdvancedCompilerBug = class( tCompilerBug)
    abc: String;
Additional InformationThe second appearance is treated as duplicates identifier although both members are private.
In my eyes this is a contradiction against the scope "private".
Best regards!

This is about the compiler, so not about Lazarus.
Please take care where (project) you post reports.

This is not a bug and by design in mode objfpc.

This is easily visible since it does compile in $mode Delphi
