Background [1]: libstdc++6 introduces a new ABI to conform to the
C++11 standard, but keeps the old ABI to not break existing binaries.
Packages which are built with g++-5 from experimental (not the one
from testing/unstable) are using the new ABI. Libraries built from
this source package export some of the new __cxx11 or B5cxx11 symbols,
and dropping other symbols. If these symbols are part of the API of
the library, then this rebuild with g++-5 will trigger a transition
for the library.
What is needed:
- Rebuild the library using g++/g++-5 from experimental. Note that
most likely all C++ libraries within the build dependencies need
a rebuild too. You can find the log for a rebuild in
https://people.debian.org/~doko/logs/gcc5-20150701/
Search for BEGIN GCC CXX11 in the log.
- Decide if the symbols matching __cxx11 or B5cxx11 are part of the
library API, and are used by the reverse dependencies of the
library.
from checking libgraphicsmagick++1{,-dev}, there are public symbols
involving std::string, so the library package needs to be renamed.

+1, I'm in the process of updating it. Will upload it today in some hours.

I attach the proposed update. As I'm again a bit overloaded, I would
be glad if someone may take a look before I upload it.

There's also a diff at
