Hi, has anybody tried the implementation of unordered map that can be found at http://groups.yahoo.com/group/boost/files/jtc1-sc22-wg21-2003-n1456.tar.gz ? I believe there is a bug in the rehash function of the underlying hash_table. The new bucket indices are computed using the old number of buckets. That means that the items stored in these buckets cannot be found anymore later. ---------- hm...it seems like you have found a bug I didn't have the time to track down :-) I checked my hash function and it seems to be right. The bug doesn't seem to show if the trivial hash function that comes with this package is used (maps val->val). BTW: what is the reason behind burying potentially useful code in a place where nobody can find it? (I mean the "yahoo groups") Is there still life in the development of this package? --------------- Probably not...it has been impossible to contact the author for some time. -Thorsten
