<pre>!- this report is related to a creation of a directive section for dll.
Clang is not generating Linker Directives for a destructor of imported with
__declspec(dllimport) class when this destructor has out-of-class definition.
Clang emits a warning:
warning: 'C3::~C3' redeclared without 'dllimport' attribute: previous
'dllimport' ignored
[-Winconsistent-dllimport] -!
