11985	range: compiler-error sub_range copy-constructor workaround for MSVC	Tobias Loew	Neil Groves	"Hi,

the following code generates an error when compiled with MSVC 11 (aka VS 2012)

{{{
    std::vector<int> arr;
    arr.push_back(42);
    boost::sub_range<std::vector<int>> ran = arr;
    boost::sub_range<std::vector<int>> ran_2 = ran;
    const boost::sub_range<std::vector<int>>& ran_ref = ran;
    boost::sub_range<std::vector<int>> ran_3 = ran_ref;
}}}



Error: libs\boost\boost\boost\range\iterator_range_core.hpp(69): error C2440: 'static_cast' : cannot convert from 'std::_Vector_const_iterator<_Myvec>' to 'std::_Vector_iterator<_Myvec>'


the reason is a 
BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1500) )
in boost/range/sub_range.hpp at line 183
if I comment out the workaround everything compiles correct.
