Upgrading libgraphicsmagick++1-dev fixes this...
It looks like libgraphicsmagick1-dev needs versioned breaks against
libgraphicsmagick++1-dev.
Perhaps this issue is due to g++ defaulting to a newer version of the
C++ standard and thus it requires a new C++ ABI?
I don't think so. I'd rather blame:
* Test build with QuantumDepth 16 (closes: #557879).
But wait, isn't change of QuantumDepth an ABI breakage?
SONAME of the non-C++ library didn't change; it's still
/usr/lib/libGraphicsMagick.so.3.
