That's because there is no custom comparison predicate for comparing bucket*. vector<bucket*> is just a list of pointers, and so uses the sort order for pointers. You'd have to set up an STL functor to sort them, which is ugly and difficult (but certainly doable). If sorting is unnecessary it's a better way to go, obviously. :-) When I comment out the sort, it works well for me. -- Hans Fugal Fugal Computing ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
