I've just tried building Data-Alias-1.19 on unmodified upstream Perl
5.22.0 with gcc 4.8.5 and 5.2.1, with and without -Dusethreads, and with
and without -fstack-protector-strong. It fails with all of these.

However, building Data-Alias-1.19 with clang works even on our packaged
perl 5.22.0-4. So the perl build doesn't seem to matter that much.

For more data points, all 5.22.0 CPAN testers seem to fail except
Darwin, which is using clang of course. Even Win32 builds fail :)

Unfortunately I don't have gcc-4.7 handy right now, so I can't say
yet if that works for me or not.

Hope this helps a bit,
