Comment (by joaquin):

 Hi Alex,

 Thank you for reporting the problem. I can't just accept your patch
 because, even f it worked, it would be masking a more serious problem,
 namely that erasing elements from a hashed index does not eventually lead
 to an empty structure where `end_->prior()==end_` --this is a fundamental
 property of the underyling data structure. So, I need to know more about
 the context where this is happening. I understand the data you work with
 is private, but could you at least show the hashing code for `std::string`
 you're using? I suspect there might be a problem with that.
