Oh, I entirely missed the fact that operator << works with paths... 
However, the following program on Linux says "Aborted".

#include <boost/filesystem/path.hpp>
#include <iostream>

using namespace std;
namespace fs = boost::filesystem;

int main()
{
     fs::path p1("/home/ghost"), p2("/a/b/c");

     cout << (p1 << p2).file_path() << "\n";
}

The problem is at
#7  0x0804c9fd in boost::filesystem::path::path (this=0xbffff878, 
src=0x804f5d2 "/home/ghost")
     at ../src/path_posix_windows.cpp:186
186           m_path_append( src );
