There is another unexpected problem with Clang on Windows.
If I add "-std=c++17" to cpp options, then in case of GUI app (example: tutorial/Gui01) in Debug configuration I get this (Release is fine):

Because STD_NEWDELETE is defined, and it gets defined in config.h here:

#ifdef  flagCLR
#define flagUSEMALLOC
#define STD_NEWDELETE
#endif

I have no idea where flagCLR is coming from ...
