So, I've tried to build 1.18.2-2 on arm64 (which suceeded in the past), and it
now fails, indicating it's indeed a problem somewhere else.
I've tried to build using g++5 and it now works fine.
So the symbol changes is due to the upgrade to gcc/g++6. I'm not sure it's
really expected, so any help appreciated.
I'm adding Matthias to CC: in case he has any idea.
Matthias: I'm experiencing a build failure in lightdm due to symbol changes in
a C++ library only on non intel arches, following upgrade to gcc6. Does that
ring you a bell or something? The changed symbols are only destructors:
