Title:
  vector subscript out of range assertion hit on windows

Status in Zorba - The XQuery Processor:
  In Progress

Bug description:
  in src/zorbatypes/binary.cpp a lot of vectors are accessed with [0],
  e.g.:

      aBase64.theData.resize(
        copy_without_ws( aString, aLength, &aBase64.theData[0] )
      );

  if in this case aLength is of size 0 the assertion "vector subscript
  out of range" is hit on windows in debug build. This happens because
  size == pos in std::vector implementation on windows:

    reference operator[](size_type _Pos)
                {       // subscript mutable sequence
     #if _ITERATOR_DEBUG_LEVEL == 2
                if (size() <= _Pos)
                        {       // report error
                        _DEBUG_ERROR("vector subscript out of range");
                        _SCL_SECURE_OUT_OF_RANGE;
                        }

  Therefore, before accessing a vector with [0] one must check whether
  the size of the vector is > 0. Otherwise the mentioned assertion will
  trigger.
