2478	Invalid assert in boost::filesystem::path::iterator	Raffi Enficiaud <raffi.enficiaud@…>	Beman Dawes	"The following code asserts (fs = boost::filesystem)


//**** Code begin

fs::path p1(""/tmp/unit/repertoire""), p2(""/tmp/unit/repertoire/."");

fs::path::iterator it1 = p1.begin(), it1e = p1.end(), 
it2 = p2.begin(), it2e = p2.end();

for(; (*it1 == *it2) && (it2 != it2e) && (it1 != it1e); ++it1, ++it2)
{}

p2 = """";

while(it2 != it2e)
{
 p2 /= *it2;

 ++it2; // <- asserts on this line (first pass)
}

//**** Code end

The assertion (DEBUG defined) is thrown on line 1342 inside file ""boost/filesystem/path.hpp"". 
Basically, the assert checks if the increment it outside of the range of iteration. However, after checking it2 != it2e, I should be able to increment it (but not the dereference it). Moreover, if 
it2 != it2e, I should be able to call ++it2.

The environnement is the following :
- Windows XP (on virtual box)
- Visual C++ express 2008 (version 9.0.21022.8 RTM)
- Boost 1.37 (I think it is the same with 1.36)"	Bugs	closed	Boost 1.38.0	filesystem	Boost 1.36.0	Problem	invalid
