I could not see that assertion in the 1.34 RC branch? Are your examples
from 1.33?

Here's the definition from 1.34:

         size_type erase( const key_type& x ) // nothrow
             iterator i( this->c_private().find( x ) ); // nothrow
             if( i == this->end() ) // nothrow
                 return 0u; // nothrow
             this->remove( i ); // nothrow
             return this->c_private().erase( x ); // nothrow

This works fine if the map is empty.

Wheter the overload that takes an iterator should be allowed to accept
the end iterator is another issue. I'll give it some thought.
