Hi,

this is related to https://svn.boost.org/trac/boost/ticket/8596 which is 
fixed now, but maybe it doesn't works for you.
Note that the trunk regression test since revision 84414 run with this 
compiler pass ( 
libs/thread/test/sync/futures/packaged_task/func_ctor_pass.cpp) 
<https://svn.boost.org/trac/boost/browser/branches/release/libs/thread/test/sync/futures/packaged_task/func_ctor_pass.cpp?rev=84468>
http://www.boost.org/development/tests/trunk/developer/thread.html.

Unfortunately not a single msvc tester has run after revision 84468 on 
release branch.

I have no the possibility to reproduce it now. Please could you send the 
whole log? (privately if you prefer? Or via a ticket?

Best,
Vicente
