Can you please try the previous revision (6889a3acfee) but with option
-fno-ipa-sra ?  If it fails, it means that the previous implementation
of IPA-SRA hid some other error (we have already had an aliasing bug
like that) - in that case it would be great if you could bisect again,
this time with this option.
