It seems very likely to me. Such kind of gcc bug is often the result
of wrongly optimized code. Building the last stage of native gcc with
-O0 or -O1 would be help to see what is going on.

I didn't make a complete native environment yet. I'm trying to build
it now. I'll look this example closely when I get a native compiler.
