OK, clear. Thing is thread is actually being join()ed by thread_group::join_all() which does not do the check. Is that a bug or I am using it wrong now too?<div class="gmail_extra"><br><br><div class="gmail_quote">2012/11/8 Igor R <span dir="ltr">&lt;<a href="mailto:boost.lists@gmail.com" target="_blank">boost.lists@gmail.com</a>&gt;</span><br>

<br>
<br>
</div>Yes, you should check that the thread is joinable or ensure that<br>
BOOST_THREAD_TRROW_IF_PRECONDITION_NOT_SATISFIED is not defined.<br>
