The binary search wasn't very difficult.  Ran regrtest with the -v and -f
flags.   test_anydbm was the only test.  Here's the output:

    % ./python.exe -E -tt ../Lib/test/regrtest.py -f tests -v -uall
    test_anydbm

    test_anydbm_modification (test.test_anydbm.AnyDBMTestCase) ... ERROR
    test_anydbm_read (test.test_anydbm.AnyDBMTestCase) ... ERROR
