If you can take the debug time hit, it might be worth your while to
install STLport, recompile using the STLport headers and use its STL
debug mode. That might provide insight as to whether the issue is with
MSes version of STL (most likely) or a code usage problem (less likely).
Either way, it'll help determine the problem. If the iterator works with
STLport, then the problem is with MS STL.
