Lack of package maintainer resources? Slipped through the cracks? You
could try opening a bugzilla against gsl asking for the version to be
updated.
affects many packages, so it takes time for all the upstream developers to
support a new GSL version. If the new version only adds new features without
breaking backwards compatibility it would be appropriate for Fedora to provide
the new version, but there may be non-trivial work to get GSL working with new
compiler versions and Fedora's rather fussy default options.
The OP's error is unlikely to be a bug in qag.c or GSL. I have worked with
some difficult numerical integrations back when the IEEE f.p. standard was
new. I recall a case where an integration that was failing on a CDC Cyber, putting
a PhD thesis in jeopardy. Moving the calculation to a (then new) PC and enabling
gradual underflow allowed the integration to complete. I assume gradual underflow
is universally enabled these days, but it is not unusual for people to ask for tolerances
that are difficult to achieve.
