 test_output fails on trivial, platform-specific output formatting
 differences. In the output below you see different forms of expected
 results: "1.#INF", "-1.#INF", "-nan", etc.

 Since (I think) C++ doesn't define these specifically, perhaps a regex
 should be used to capture all variants.

 Other platform failures are similiar.
