[fpc-devel]Bug or missing documentation?

[BiPolar]

Hello.

The code below gives: "foo.pas(13,33) Error: Duplicate identifier NAME"
when compiled with -S2. It compiles ok with -Sd though.
The thing is, I coudn't find any reference to this difference of 
behavior under the "Compiler Modes" section of FPC docs, neither in 
other sections.
Is this a bug, or I missed something in the docs?

Thanks for your time and work.

procedure TChildClass.Test(aName : string);
begin
// do nothing.
