Possibly relevant: Fedora at least are forcing some compiler options which sometimes result in precision issues (https://src.fedoraproject.org/rpms/gsl/blob/rawhide/f/gsl.spec#_43).

Let me know if I can provide more useful information. It seems like there's been an improvement for sparc because IIRC 2.6 SIGBUS'd when running tests but I never got a chance to report it.

Initially reported downstream in Gentoo at https://bugs.gentoo.org/805578.

The failures have been observed on both ppc64 and sparc, looking like:
