Comment (by phreakuencies@…):

 Hi,
 I'm using gcc 4.9 (on archlinux) and had this bug (complained about
 deleted operator on stored_edge_property), which appeared when using
 adjacency_list with listS/vecS.
 I added this patch and it did not change the behavior (bug still appears).
 I noticed it is only enabled on a specific version of GCC and thus I
 removed that condition but it made no difference. I looked into the .hpp
 file (unpatched) and noticed there was a similar condition for
 stored_edge_property, which now looks like this and the bug disappeared
 (changed first line of this code):

 {{{
 #if defined(BOOST_MSVC) || (defined(BOOST_GCC))
       stored_edge_property(self&& x) : Base(static_cast< Base const& >(x))
 {
         m_property.swap(x.m_property);
       }
       stored_edge_property(self const& x) : Base(static_cast< Base const&
 >(x)) {
         m_property.swap(const_cast<self&>(x).m_property);
       }
       self& operator=(self&& x) {
         Base::operator=(static_cast< Base const& >(x));
         m_property = std::move(x.m_property);
         return *this;
       }
       self& operator=(self const& x) {
         Base::operator=(static_cast< Base const& >(x));
         m_property = std::move(const_cast<self&>(x).m_property);
         return *this;
       }
 }}}
