What does 'illegal indirection' mean?

The code is simple:

// Token.h
#ifndef TOKEN_H
#define TOKEN_H

#include <vector>
#include <string>

class Token
{
public:
    Token() : type("word"), positionIncrement(1), startOffset(0),
endOffset(0) {}
    void setPositionIncrement(const unsigned int increment)
    {
        positionIncrement = increment;
    }
    unsigned int getPositionIncrement() const
    {
        return positionIncrement;
    }
    void setTermBuffer(const std::vector<char>::size_type&,
        const std::vector<char>::size_type&);
private:
    std::vector<char> termBuffer;
    std::vector<char> payload;

    unsigned int startOffset;
    unsigned int endOffset;

    std::string type;
    unsigned int positionIncrement;
};

#endif

// Token.cpp
#include <algorithm>
#include <iterator>

#include "Token.h"

using std::copy;
using std::back_inserter;

void Token::setTermBuffer(const std::vector<char>::size_type& b,
                          const std::vector<char>::size_type& e)
{
    copy(b, e, back_inserter(termBuffer));
}

The setTermBuffer function is used to copy a vector into the
termBuffer vector.
But I got an error: 'error C2100: illegal indirection'
What does it mean?

BTW, as I include <vector> in the header file,
the cpp file include the header, need I add '#include <vector>' the
cpp file?
