I think the source code comments in the test program below answer your question. Bart. $ cat drd/tests/std_thread.cpp // Test whether no race conditions are reported on std::thread. Note: since // the implementation of std::thread uses the shared pointer implementation, // that implementation has to be annotated in order to avoid false positives. // See also http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html for more // information. #include "../../drd/drd.h" #define _GLIBCXX_SYNCHRONIZATION_HAPPENS_BEFORE(addr) \ ANNOTATE_HAPPENS_BEFORE(addr) #define _GLIBCXX_SYNCHRONIZATION_HAPPENS_AFTER(addr) \ ANNOTATE_HAPPENS_AFTER(addr) #define _GLIBCXX_EXTERN_TEMPLATE -1 #include <iostream> #include <thread> int main(int argc, char** argv) { std::thread t( []() { } ); t.join(); std::cerr << "Done.\n"; return 0; } ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
