Re: [boost] no matching function for call to boost::algorithm::split

Ok, I see the problem now. You cannot pass a temporary value into the split
algorithm.

The reason for this comes from a possibility to store result in a container
of iterator_range's. In other word, the result will be just a reference to the
input. 

So to workaround your problem, simply create a local variable, that will hold
the input.

Pavol
