The following tests were added during the 1.7 cycle to demonstrate bugs: alpha-similar operator operator-alpha self-copy-overlap In all cases, the identical bug existed in the last major release, (1.6.4), so these are not new regressions, but merely bugs that we're now aware of. The correct way to handle bugs such as these is to mark them as expected failures (XFAIL).
