I've been using Boost Multiindex quite a lot but don't understand why the code below inserts two items. The container has a unique hash index and the two items return the same hash value. Is this is a bug in the library or in my code? [...] indexed_by > >

Here's the problem: your key is shared_ptr<foo>, i.e., you compare *the pointers* rather than the pointed to foo objects. What you want is this instead:

thanks for your fast answer! But the hash function is still hash_value(const shared_ptr<foo> &f) or hash_value(const foo &f)? Boris
