[Boost-users] Boost.Thread memory leak reported

HI,

There is a small memory leak reported by VC7.1 just by declaring a
boost::mutex (presumably).  Since this makes no sense at all, perhaps
there is some explanation for this behavior in this compiler.  The code
looks like this:

In the class definition:

mutable boost::mutex m_orphan_annotation_mutex;

(It's only declared mutable because it's used in 'const' methods also).

In the .cpp file:

void OrphanedAnnotationMap::IndexOrphanedAnnotations()
{
        boost::thread indexer(
                boost::bind(&OrphanedAnnotationMap::Index, this));

        boost::mutex::scoped_lock lock(m_orphan_annotation_mutex);

        indexer.join();
}

The memory dump is this:
