problem with boost::algorithm::split

[liner]

string str("*word1-word2*word3-");
vector<std::string> ResultCopy;
split(ResultCopy, str, is_any_of("-*"), token_compress_on);
for(unsigned int nIndex=0; nIndex<ResultCopy.size();
nIndex++)
{
    cout << nIndex << ":" << ResultCopy[nIndex] << endl;
};

The output is:
0:
1:word1
2:word2
3:word3
4:

Is this a bug?

In my opinion the output should be:
0:word1
1:word2
2:word3

The current behaviour is not a bug, rather the former one
was not correct.
Based on the long discussion on both developer's and user's
list, the implementation was changed to always return 
n+1 tokens where n is number of separators. No empty tokens
are removed, event if they are on the endings of the input
string.

You can simulate the deprecated behaviour simply by trimming
the input before the split operation. 
Just add 
boost::trim_if(str, is_any_of("*-") 
before split.
