Comment(by niels_dekker):

 The
 [https://svn.boost.org/trac/boost/attachment/ticket/3869/value_init_workaround.patch

 value_init_workaround.patch] I just attached should resolve this ticket.
 It assumes that the defect macro BOOST_NO_COMPLETE_VALUE_INITIALIZATION is
 defined for those compilers that need it (ticket #4080). Note that it adds
 an extra macro, BOOST_DETAIL_VALUE_INIT_WORKAROUND (defined as either 0 or
 1), which controls whether the memset workaround is applied. This macro is
 merely intended as an implementation detail: I would like to have an extra
 test which toggles the value of the  macro, in order to check if the
 workaround is both effective and necessary.
