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:

QDBusError::~QDBusError()
QByteArray::~QByteArray()
QHash::~QHash()
QString::~QString()

Well, as assumed, the build fails on i386/amd64 with the updated symbols file.
I might be able to provide multiple symbols file but it does look weird in any
case.

I have to admit I'm not really comfortable *removing* symbols from a file just
for some architectures. It looks weird to me that it would only happen on
those arches. Maybe something changed in Qt but I'm highly puzzled here.

Full build log:
https://buildd.debian.org/status/fetch.php?pkg=lightdm=mips=1.18.2-3=1476913394

The problem is in liblightdm-qt-3-0.symbols where these symbols are missing.

I have created and attached a patch that adds missing symbols into this file 
and resolves this issue.
With this patch package builds successfully on mips*, i386 and amd64 
architectures.
