--- Comment #4 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
After checking for possible other execution paths, it looks like the proposed
patch will work fine.  It is more obvious then that, the fnode is a local
declaration.

I will commit this one as "obvious" after passing regression tests.
