Comment (by Craig Hutchinson <craig@…>):

 Okay so I have tested a Haswell i5-4670 and with 2 thread the issue too
 53,161 executions to occur, however up the test to 4 threads and the crash
 occurs every 2-4 executions! I don't know that that really indicates as on
 the i7 two threads was causing the issue so could be amplified by hyper-
 threading somehow.

 I don't like the 'fix' but putting a mutex lock around the constructor for
 the coroutine is the only work around I have currently found
 {{{
 {
 boost::lock_guard<boost::recursive_mutex> lock(m_guard);
 coro_t::pull_type( boost::bind( foo, _1, i) );
 }
 }}}
