--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> --- I've downloaded nettle-3.0 from http://ftp.gnu.org/gnu/nettle, built it with the default options (-O2) with last week's trunk (5.0.0 20150303) and the system GCC 4.8.3 on a ppc64le box running RHEL 7.1, and ran the test suite. There are the following two failures in both. I'll look into the camellia test failure next. ...
