11 years ago This is fixed in trunk, or at least mostly fixed -- there are still a few edge cases where the warning will fire, but not your project.
(Dave, for now all of the main analyzer engineers do work at Apple, so there's no real need to file duplicates. The LLVM people who don't work at Apple don't have access to Apple Clang, which ships with Xcode, and this fix didn't make Xcode 4.6. You can also get newer checker builds from http://clang-analyzer.llvm.org)

Extended Description
Analyze the attached code with clang. We are using Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn) that shipped with the Xcode 4.6 GM. By code analysis we think it exists in TOT clang. We think the code is fine and we are getting a false positive with regards to init.
