Dear maintainer(s),

I looked at the results of the autopkgtest of your package because it 
showed up as a regression for jq. I noticed that it regularly fails on 
s390x since March 2025 and it now fails more often than it passes.

I recall there was something special with NaN on s390x, but I can't find 
it. Maybe I'm mixing up with ppc64el which recently was on my radar 
because of another NaN bug.

Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul
