On both sparc-solaris and sparc64-solaris, top (as provided by unixtop) segfaults or bus errors when executing. The issue appears to be caused by high thread ids [1]. Running the sample program in the mentioned bug causes top to reliably segfault. After applying the upstream mentioned patch [2] (also mentioned in [1]), top no longer segfaults when running with the sample program. Please see to applying the patch in gentoo.
