Thank you for bringing this up.  I'd let to get the checker in too.
But, I don't really understand the regrename.c patch.  Are you saying
that regrename.c is broken, and that we need to make these copies
because of a real bug?  Or just to make the checker happy?  If the
latter, have you measured the compile-time and memory usage to see what
impact that has?  We'd like to avoid making the compiler slower just to
make the checker happy -- but, of course, it might be worth a small hit
to get the checking benefit.

Thanks,
