Hi, I brought an older dual G5 Powermac back to life and installed FreeBSD 10.0-RC4 on it with a GENERIC ppc64 kernel. When installing lang/ruby19 or lang/ruby20 miniruby segfaults in libthr. Tested with both the default gcc42 as well as with gcc49.
Has anyone seen this issue before? T
Thanks & cheerio, Harry.
