New description:
{{{
sage: N(integrate(sin(x^2)/(x^2), x, 1, infinity))
[...]
ValueError: Integral is divergent.
}}}
This worked fine until v4.5.3, fails from v4.6.1 onward.
The expected output (with Maxima 5.29.1) is:
{{{
0.285736646322858
}}}

Comment (by dimpase):
Both new Maxima and Wolfram Alpha give the value about 0.2857367, and not
0.28625044 (what you see in the ticket description). Changing the latter
to reflect the reality.
