I hit this issue building boost 1.44.0 with gcc trunk last night. The
following patch works around the ambiguity by using const_group_iterator
instead of just group_iterator. Don't know if this is an issue with
boost or gcc but this got it building for me.
Note that I don't know about any performance or run-time issues this
patch may cause -- I just wanted to get it built.
