That looks like the correct result to me.

Interesting.

The "==" to "=" change was fine, and there is now a patch in the repo
for that anyway.  You say that your gcc gives random crashes.  My best
guess is flaky hardware - bad memory.  Maybe there was some random
corruption in gcc whilst building something in the runtime system.  I
would try
    rm targets/powerpc-Darwin8/obj/runtime
    rm targets/powerpc-Darwin8/runtime
    make runtime
and see if you get the same behaviour.
