That's ... weird. I don't have RHEL7 installed to test, but I don't
see any error for that value on RHEL6 or Fedora 25, which ought to
bracket that version.
I suppose your version of strtod() must be refusing to do gradual
underflow, or else you're running on hardware that doesn't do
IEEE-compliant arithmetic. But I didn't think RHEL supported any
such hardware (unless maybe it's s/390?). And I can't find any
documentation suggesting that glibc supports turning off gradual
underflow, either.
Perhaps you're using some extension that fools around with the
hardware floating-point options?
