If this compiles, your compiler is broken.

It didn't

And replacing m_main
with k_main shouldn't change anything here.

It works with g++.

That's a known bug in g++.


  pthread_join( m_thread, NULL);

pthread_join can block. I'm not sure its a good idea to
call it from a destructor. (Destructors are called during
stack walkback, in case of an exception. Which is generally
a context where you don't want to block for an indefinite

I'll have to think of a way of tidying up if exceptions are

It is a problem:-). And I don't know of a good solution.
(Boost detaches the thread, which is even worse than doing the
join.) What you want to do is to force the other thread to
terminate as rapidly as possible, and then join. But at least
at present, pthread_cancel doesn't work (portably) in C++, and
even if it did, it's largely advisory, at least in some of it's
