I couldn't find information how to do it. Here is
http://clang.llvm.org/docs/UsersManual.html#analyzer_diagnositics
how to completly disable analyzer for a pice of code but it still needs
changes in code. And it isn't good solution neither.
Maybe it would be good to describe problem on clang-dev mailinglist?
