[Boost-users] [Assign] Error using list_of() with Visual C++ 2010 Beta 1

In the Boost.Assign documentation, the following example of list_of() is given:

const list<int> primes = list_of(2)(3)(5)(7)(11);

However, I have tended to write this instead:

const list<int> primes(list_of(2)(3)(5)(7)(11));

This is causing problems with the Microsoft Visual C++ 2010 Beta 1
compiler. Using Visual C++ 2008, both lines compile fine but with 2010
Beta 1, the second produces the following error:

error C2668: 'std::list<_Ty>::list' : ambiguous call to overloaded
function with [_Ty=int]
could be 'std::list<_Ty>::list(std::list<_Ty> &&)' with [_Ty=int]
or       'std::list<_Ty>::list(unsigned int)' with [_Ty=int]
while trying to match the argument list
'(boost::assign_detail::generic_list<T>)' with [T=int]

Is this:

   a) My fault? Should I be using copy initialization rather than
direct initialization?
   b) A problem with the 2010 beta compiler?
or c) A problem with Boost.Assign?

Thanks
