Comment (by ned14):

 Excellent to see this bug report - I can confirm this bug. My GSoC student
 candidates found it during the programming task I set them two weeks ago.
 It causes substantial memory corruption throughout the process.

 I might add I saw different behaviour between BOOST_THREAD_VERSION=3 and
 BOOST_THREAD_VERSION=4. This may be important.

 C++11's std::packaged_task<> is very clear that it takes a '''copy''' of
 the passed callable. I appreciate that compiler oddities may make that
 hard.
