Hm.  I tried this trivial patch:

   return decl;

and when I check in gdb the trees are marked as addressable [checking in
objc-act.c/finish_var_decl() ].
... but something is un-doing this later - and _OBJC_CLASS_REFERENCES_0 is
ending up marked as not tree addressable according to the ipa dump.

any ideas where I'm going wrong?
