clang report files generated in home folder

This is an issue report from Korean customer(Samsung). When QtCreator clang plugin somehow fails to create temporary directory(by access denial or storage full), it creates report files in HOME folder. We wonder if this behavior is intended or not. Also, are there some fallback methods to create files in another directory?
