There definitely are. (And some subtle ones, reading from upstreams commits
for 5.2.x)

That one's fixed by http://cgit.freedesktop.org/libreoffice/core/commit/basebmp/inc/packedpixeliterator.hxx?id=352f9fdff619b5a0a1414c29cfc47068165a599c
(actually in 5.2.x the whole thing is gone.) but there definitely are more.
See https://whatofhow.wordpress.com/2016/01/20/gcc-6/.
And when trying it on 5.1.x I get a ICE :/
(actually Stephans post above says two ICEs, one of them can be worked around
in LO, the other one (PR 69327) is to be patched in boost but at least in my
attempt[¹] I didn't run into a ICE. But if it happened we'd need a patched boost
and/or we wait for a fixed gcc 6...)
TL;DR: Will be fixed in 5.1 packages.

Rene
