Fix: declaration of * hides class member

[feniksa]

On VS 2019 warning "C4458: declaration of '*' hides class member" . As result, projects that have -Werror can't compile due this warning.

Hm, I don't think that verification error somehow connected with changes

I stumbled upon this because of the same warning firing. Just to add my two cents, but in C++ names beginning with an underscore followed by a capital letter are reserved for standard library as per 17.4.3.1.2 of the standard:

Certain sets of names and function signatures are always reserved to the implementation:

    Each name that contains a double underscore (__) or begins with an underscore followed by an uppercase letter (2.11) is reserved to the implementation for any use.
    Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.165

165) Such names are also reserved in namespace ::std (17.4.3.1).
