Using Clang 9 on Windows  b2 toolset-clang-linux cxxstd=2a  .

I am seeing lots of these warnings

In file included from ..\..\..\boost/test/included/unit_test.hpp:23:

In file included from ..\..\..\boost/exception/diagnostic_information.hpp:11:

[-Wdelete-non-abstract-non-virtual-dtor]
                    delete this;
                    ^
It seems that trying to supress is ineffective with 

  -Wno-delete-non-abstract-non-virtual-dtor

Perhaps by design?

Should I be concerned about this?
