thread-sanitizer

I am having a problem with Gcc's thread sanitizer that I cannot find on their bugzilla or on stackoverflow so I am unsure if I am missing something or if this really is a bug. If I create a main.cpp file containing: #include <thread> int main(){ std::thread t([](){}); t.join(); return 0;} Now if I compile it using: g++-4.9.2 -std=c++1y -fsanitize=thread -fPIE -pie -o TestProgram main.cpp Running the resulting executable does not yield any problem. Yet if I add the debug info flag: g++-4.9.2 -std=c++1y -fsanitize=thread -g -fPIE -pie -o TestProgram main.cpp then the thread sanitizer detects a

Please have a look at the following code: #include <pthread.h> #include <boost/atomic.hpp> class ReferenceCounted { public: ReferenceCounted() : ref_count_(1) {} void reserve() { ref_count_.fetch_add(1, boost::memory_order_relaxed); } void release() { if (ref_count_.fetch_sub(1, boost::memory_order_release) == 1) { boost::atomic_thread_fence(boost::memory_order_acquire); delete this; } } private: boost::atomic<int> ref_count_; }; void* Thread1(void* x) { static_cast<ReferenceCounted*>(x)->release(); return NULL; } void* Thread2(void* x) { static_cast<ReferenceCounted*>(x)->release(); return
