--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ah, ISTR this from another bug where I wanted to investigate but never got
along doing that ...
Well for DOM the issue here is that it doesn't handle the aggregate init
a = *.LC0;
followed by a partial read from a.
But I wanted to analyze why FRE can't handle this either - sth I'll now do
with a modified pass pipeline (though fixing that won't help you here).
