11390	Wrong type in dynamic_bitset::reference constructor	stefan.atev@…	jsiek	"When compiling with visual studio 2013, the following warning is issued (and since we treat these as errors, fails the compilation):

boost/dynamic_bitset/dynamic_bitset.hpp(298): warning C4267: 'argument' : conversion from 'size_t' to 'unsigned long', possible loss of data

The culprit is the reference constructor:

reference(block_type & b, block_type pos)

which should be:

reference(block_type & b, block_width_type pos)

used in the non-const accessor:

reference operator[](size_type pos) {
        return reference(m_bits[block_index(pos)], bit_index(pos));
    }

bit_index() is defined as returning block_width_type, not block_type (which may be narrower).

The const accessor works as expected and is a possible workaround when read-only access is required from a non-const bitset."	Bugs	new	To Be Determined	dynamic_bitset	Boost 1.58.0	Problem
