This flag results in calls to (at least) isfinite() and isnan() becoming skipped, and a constant false returned. This caused volume-test to fail on Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=916504 Since PulseAudio deals with negative infinities with volume dB values, this is not a problem only in volume-test. We shouldn't use -ffast-math at all.
