Yes. During the import of the body we import a `DeclRefExpr` which refers to a `ParmVarDecl` but not the existing one, thus a new is created. > Maybe it works in VisitParmVarDecl to search for already existing ParmVarDecl > (not already imported) and return if found. Yes it would worth to try, indeed.
