>Description:
The file attached exposes a regression from the current cvs 
g++ WITH libstdc++-v3 enabled with respect to 2.95.2.
I believe the code is legal...
g++-2.95.2 accepts it without a complaint.
The current version (with libstdc++-V3) gives:
vanuatu->/net/home/robotvis/gnu/egcs/bin/g++ map.C
map.C: In function `int main()':
map.C:14: no match for `std::_Rb_tree_iterator<std::pair<const int, const int>, 
   const std::pair<const int, const int>&, const std::pair<const int, const 
   int>*>& != std::_Rb_tree_iterator<std::pair<const int, const int>, 
   std::pair<const int, const int>&, std::pair<const int, const int>*>'
>How-To-Repeat:
Compile the attached file with a recent libstdc++-v3 enabled 
compiler should be sufficient.
