On an emulated UltraSPARC system running Linux (and using V9 ABI) I was
able to build the RC, but get a SIGBUS when running ring_c.
The problem is an unaligned 64-bit access, as shown by the gdb session
below.
I have not tried, but it *might* be possible to reproduce on PPC64 via
"prctl --unaligned=signal".

Core was generated by `examples/ring_c'.
Program terminated with signal 10, Bus error.
