--- Comment #14 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
Thanks,  Those cases seem fixed now.

I do however still see another LTO failure that looks related in SPECCPU 2006:

I will reduce and bisect this morning and will close this tickets and file a
new one if not.
Still waiting on the results of the other non SPECCPU workloads, but so far
looks good!
