inconsistent behaviour of const_iterator and const_reverse_iterator

[Serengeti]

hello,
I've had some hard time trying to understand why does this code
compile:
http://cpp.sourceforge.net/?show=10151 (*)
while this doesn't:
http://cpp.sourceforge.net/?show=10150 (**)

Any insights would be greatly appreciated.

#include <vector>
using std::vector;

int main()
{
vector<double> vect;
for(vector<double>::const_iterator v = vect.begin(); v !=
vect.end(); v++);
}

(**)
#include <vector>
using std::vector;

int main()
{
vector<double> vect;
for(vector<double>::const_reverse_iterator v = vect.rbegin(); v !=
vect.rend(); v++);
}

This is a defect:
