[cfe-dev] How to filter some bugs from scan-build?

[Anna Zaks]

Howard,

Pragmas cannot be used to suppress the static analyzer warnings. Most likely you've silenced a regular compiler warning within Xcode.

Please, refer to http://clang-analyzer.llvm.org/faq.html for more information about how various analyzer warning could be silenced.

Cheers,
Anna.
