--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
The problem is that the expression is (internally):
a->REF_COMPONENT("_data")->REF_ARRAY(full array)
In find_array_spec, the code firsts gets the array as:
as = CLASS_DATA (e->symtree->n.sym)->as;
And then it walks the refs. Result:
a->(full array)->_data->(full array)
But having two full arrays is invalid! Hence, it fails.
(find_array_spec doesn't see that the two arrays refs are identical.)
