my guest is because LLVM ? i have Apple LLVM compiler 3.1

Thanks!

Edit:
Xcode Version 4.3.3 (4E3002)

Answer 1

I have a file that always crashes clang when analyzed. I submitted abut report on it and Apple dupped the bug – so obviously they know of some bugs already. Note that Xcode 4.4 will be released in a week or two with llvm 4.0 so just wait for it, and if you still get crashes please enter a bug report at bug reporter.apple.com

Edit: my bug report was against 4.3.3
