WaitObjectsTracer causes dirty compile under VS2015

[noloader]

Maximilian Zamorsky reports WaitObjectsTracer causes dirty compile under VS2015:

1>  network.cpp
1>...\cryptopp\wait.h(141): error C2220: warning treated as error - no 'object' file generated
1>...\cryptopp\wait.h(141): warning C4589: Constructor of abstract class 'WaitObjectsTracer' ignores initializer for virtual base class 'Tracer'
1>  ...\cryptopp\wait.h(141): note: to simplify migration, consider the temporary use of /Wv:18 flag with the version of the compiler with which you used to build without warnings
1>  ...\cryptopp\wait.h(141): note: virtual base classes are only initialized by the most-derived type

This appears to be a bug in Visual Studio 2015; see VS 2015 generates a copy constructor and then complains about it on Microsoft Connect.

Added tags Invalid and Bug. It was marked Invalid because its a Microsoft bug. it was marked as Bug because we are going to work around it for library users.

Have you tried VS 2015 Update 1? The bug report on Microsoft Connect is now "Closed as Fixed".

@Zireael-N - No, I don't have a working copy of Visual Studio 2015.

The Community Edition is free, but it looks like you need to open some type of account to receive the free license. I was able to find information here:

Not really, you can just download it here: https://www.visualstudio.com/downloads/download-visual-studio-vs

If you check Jeff's link to Stack Overflow, the problem is not the download (he has the Community Edition) but that he has not taken the steps necessary to activate the free license beyond the trial period.

Oh, I didn't expect that link to be leading to a question on Stack Overflow.

At one point after the installation VS did ask me to sign in into MS account, I have one so I guess that's why I didn't have a trial period. You can make one here: https://signup.live.com/signup

Working as part of Issue 214: VS2015 and multiple C4589 warnings, "Constructor of abstract class X ignores initializer for virtual base class Y".
