===================
138 tests passed.
6 tests failed.
Observations:
All failing tests seem related to complex multiplication and division.
Before clang even gets involved, 3 tests fail using system gcc -- TODO dig into
tests, and find out which comparisons are failing.
Then when clang is used, 3 more tests fail. Is this a result of
miscompilation?</pre>
