Re: [Boost-users] hash set crashing during iteration (boost 1.35.0)

Oh phooey, I wonder if this is a 64 bit issue.  I should have
mentioned that.  I'm compiling for 64 bit address space, pointer
sizes, etc., I think it actually might have something to do with that.

Watching it in the debugger it gets into hashtable_node.hpp
(boost::intrusive::detail::bucket_impl<Slist> during the iterator
increment and comes back with a crazy number from this operation in
(get_bucket_num):

      //Now just calculate the index b has in the bucket array
      return &b - &first_bucket;

it is subtracting two addresses to arrive at the next bucket number
and I think this is probably where my problem lies.

Thank you
