Hmmm... Appveyor CI doesn't have problems with it, but of course it
ought to be newer version. Newer than 10.0 that is, judging from
reference C:\Program Files (x86)\Microsoft Visual Studio 10.0\ above.
And I can't reproduce it with 10.0... Oh wait! It's actually specific to
--debug build! I mean it might happen that it's not version-specific...
