c2039 VS2012 build erros

edit

While compiling the master from github (eff21788a80738db8b0a5901c21e447ff9134d96) on VS2012 (ultimate) under Windows 8 in 32bit mode, I get the following error(s) in Debug mode:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\xutility(364): error C2039: 'iterator_category' : is not a member of 'cv::MatIterator_<_Tp>'

In Release mode the error does not appear. Is it a bug?
