c++ - 嵌套的 boost::assign:list_of 在 Visual Studio 2012 中损坏 - 对重载函数的调用不明确

Question

这适用于 Visual Studio 2010，但不适用于 2012 Update 2(使用 Boost 1.5.3):

vector<vector<BYTE>> data = assign::list_of (assign::list_of (0x06)(0x02));

编译器给出的错误(已更新):

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\xmemory0(617): error C2668: 'std::vector<_Ty>::vector' : ambiguous call to overloaded function
   with
   [
       _Ty=BYTE
   ]
   C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\vector(786): could be 'std::vector<_Ty>::vector(std::vector<_Ty> &&)'
   with
   [
       _Ty=BYTE
   ]
   C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\vector(693): or       'std::vector<_Ty>::vector(unsigned __int64)'
   with
   [
       _Ty=BYTE
   ]
   while trying to match the argument list '(boost::assign_detail::generic_list<T>)'
   with
   [
   T=int
   ]
... (dozens of more lines)

有什么方法可以解决这个错误？

我认为问题不是来自嵌入，而是来自使用 list_of 创建临时值。这应该有效:

vector<BYTE> temp = assign::list_of (0x06)(0x02);
vector<vector<Byte> > data = assign::list_of(temp);
