Can't reproduce on (only slightly modified) trunk, might be latent there now.
Investigating on the branch instead.

--- Comment #6 from Martin Sjölund <martin.sjolund at liu dot se> ---
Thank you. I can confirm our compiler again bootstraps using gcc 5 branch using
-O2. Sadly, -O2 gives different behaviour than -O1, so I will need to
investigate and possibly file another bug report.

Already. I'll open a new issue then. Just a second.
