Well, at least the compiler tells you where to file a bug report. Hopefully they respond quickly.
It might be interesting Eric if you can list here some of the other places where you also see the error. Just for fun, maybe try the function without the always_inline. Or write out the inlined code from the various places that call the function, instead of calling the function. Other possibilities are using a different representation for 10e-6 but that would be pretty crazy if it made a difference. Almost as crazy would be that changing the value would make a difference. Also maybe test with a different version of the compiler.
