But wouldn't that mean that a program that's not in the archives (a commercial program, for instance) which depends on a C++ library libjoedoe.so.23 in Jessie will not work any more because there's going to be libjoedoe.so.23 compiled with the g++-5 ABI in Stretch. And we're not going to do that, right? (Sorry for being a nuisance.) -richard.
