Follow-up Comment #1, bug #47964 (project octave):
The following condition at line 392 of the rational_approx function is failing
the first time through the loop, so the returned string is "0":
if (fabs (frac) < 1 / static_cast<double> (std::numeric_limits<int>::max ()))
where the value frac is exactly equal to 1.0/2147483647.

My i386 build is also done with -O0, if that makes a difference here.
