--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
It turns out that GCC 4.5 was able to diagnose all three instances but that
ability was lost with r164688 so this is a regression, albeit an ancient one.

* tree-ssa-ccp.c (fold_ctor_reference): New function.
(fold_const_aggregate_ref): Use it.
* fold-const.c (canonicalize_constructor_val): Check that we don't fold
into external static.
