    Another flag bites the dust. This time: -ffinite-math-only. · 83bdd427

    Since GCC 5, with this flag set, NaN compares equal to zero in some cases but
    not others. Causes e.g. "attempted division by zero" error spam from this QC
    float x = nan("");
    if (x == 0) {
      return 0;
    return 1.0 / x;
    Yes, those NaNs should not be happening in the first place, but suddenly
    passing some but not all equality checks to zero seems rather dangerous.
    Reference: issue #2412 (not a fix for it; the QC code has a problem too but
    this change helps track it down properly).
