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.
