Description

When execute command:

rootcling -v2 -f dict.cxx RtObj.h RtObjLinkDef.h

Got a lot of failures like:

Warning: FindScope got an invalid tag decl
ERROR: FindScope about to return an invalid decl
Warning: FindScope got an invalid tag decl
ERROR: FindScope about to return an invalid decl
...

Problem can be fixed if replace #include <TObject.h> by #include <TNamed.h>,
but in my mind rootcling should avoid printing so many misleading messages.

Reproducer

Files are from roottest/root/io/clones directory:

RtObj.h
RtObjLinkDef.h

ROOT version

Master

Installation method

Build from source

Operating system

OpenSUSE
