So it's only when you have the dynamic allocation but you don't get an exception. How did you find that there is any leak? Do you have a test program?

Hi, I'm using vc.net with a tool called "Visual Leak Detector". As I said, when build the boost::thread on the stack or doing dynamic allocation with another thread library (asio socket lib, asio::thread), no leaks are reported. For my purposes asio::thread is sufficient, even though it only provides basic thread functionality. Here is the code and the memory dump: #include "vld.h" // for memory leak detection #include <boost/thread/thread.hpp> void doNothing() {} int main() { boost::thread* thrd = new boost::thread( &doNothing ); thrd->join(); delete thrd; return 0; } Visual Leak Detector Version 1.0 installed (multithreaded static). Der Thread 'Win32 Thread' (0xe54) hat mit Code 0 (0x0) geendet.
