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
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.
