This change mentioned in the GCC 4.9 news:
Improved support for C++11, including:
The associative containers in <map> and <set> and the
unordered associative containers in <unordered_map> and
<unordered_set> meet the allocator-aware container
requirements
is an ABI incompatible change in the unordered_{map,set} classes built in c++11
mode. The libstdc++6 library itself is not affected, so instead of having a
libstdc++6 transition, all packages providing a library built in c++11 mode and
using the unordered_{map,set} classes should be transitioned (changing the name
of the library package).
A grep of all sources for #include *<unordered_{map,set}>, and then searching in
the log files for usage of -std=c++{0x,11} did show the following packages
building library packages (for packages not having verbose build logs I had to
look into the source package):
bobcat 3.22.00-1
c++-annotations 9.9.1-2
capnproto 0.4.0-1
condor 8.0.6~dfsg.1-1
liblo 0.28-3
mrpt 1:1.0.2-1
qtbase-opensource-src-gles 5.2.1+dfsg-1
rapicorn 13.07.0~ds0-1
shogun 3.2.0-2
tesseract 3.03.03-1
zeroc-ice 3.5.1-6
For those transitions should be considered.
