--- Comment #4 from Nathan Sidwell <nathan at gcc dot gnu.org> ---
yes, must be something with a 32-bit target.  I can reproduce it on x86_64
linux host targeting either i386-linux or i386-solaris. 

We have a TYPE_DECL whose TREE_CHAIN points to itself.  So when the spelling
corrector iterates over the decls in a namespace it gets stuck at that point.

It's end of day here, so don't expect more progress until tomorrow.
