[Boost-users] Does boost::thread_group::create_thread have memory leak?

17 Jan 2007

      I've been trying to track down memory leak being reported by valgrind.
There are others out there who appear to have the same problem, but I
can't find any reference to it in the boost list archives.

I know valgrind can be inaccurate, but it seems pretty accurate every where
else in my program.  I've narrowed it down to something like this:

-----------------
  #include <boost/bind.hpp>
  #include <boost/thread.hpp>
  #include <iostream>

    void fn(){
      return;
      }

    int main()
      {
          boost::thread_group thrd;
          thrd.create_thread(boost::bind(&fn));
          thrd.join_all();
          return 0;
      }

-----------------

Valgrind is showing this:

...
by 0x4053D76: boost::thread_group::create_thread(boost::function0<void,
std::allocator<boost::function_base> > const&) (in
/usr/lib/libboost_thread-mt.so.1.33.1)

LEAK SUMMARY:
==22004==    definitely lost: 0 bytes in 0 blocks.
==22004==      possibly lost: 144 bytes in 1 blocks.
==22004==    still reachable: 0 bytes in 0 blocks.
==22004==         suppressed: 0 bytes in 0 blocks.

Any clues? Thoughts?

Thanks,

Pete
