Yes. That's what PR gold/19823 is about. I claim that GCC PR 55012
should have been resolved as "working as intended", and that your
patches for GCC PR 65248 should never have been applied (curiously, I
can't find any actual approval for the GCC patch). I'm sorry I missed
those conversations -- I would have raised bloody hell at the time.
I'm surprised that no one else did.
