Oh, yes, it is wrong, I overlooked that on my previous post. 
erase(iterator) does not
return a count of erased elements but an iterator to the element 
following the one that
was erased. It is erase(const key_type&) that returns a count. This is 
documented
at http://tinyurl.com/3k728t and mimics the interface of STL associative 
containers.
