Example:

    class BrokenMapping:
        def __getitem__(self, key):
            1/0
    
    # this silences the ZeroDivisionError and raises KeyError('world')
    'hello {world}'.format_map(BrokenMapping())

I have tried this on several different CPython versions on Ubuntu 14.04
(including the latest Python 3.7.0a0 from github) and they all do this.
PyPy passes the ZeroDivisionError through correctly.
