Wow, I am surprised that -ffast-math triggers a mode switch in the FPU in part due to the author's library problem, but also because the documentation for clang at least[1] does not say it impacts behaviour of denormals and in fact has a separate mode switch for that, which is not explicitly called out as being implied by -ffast-math.
