The analyzer does not model C++ temporary destructors completely and so reports false alarms about leaks of memory allocated by the internals of shared_ptr: std::shared_ptr<int> p(new int(1)); p = nullptr; // 'Potential leak of memory pointed to by field __cntrl_' This patch suppresses all diagnostics where the end of the path is inside a method in std::shared_ptr. It also reorganizes the tests for suppressions in the C++ standard library to use a separate simulated header for library functions with bugs that were deliberately inserted to test suppression. This will prevent other tests from using these as models. rdar://problem/23652766 llvm-svn: 274691
