** Description changed: + [Impact] + + * with gcc-5 default, and llvm-3.4 built with the gcc-4.9, people can't + link programs using cxx11 support + + [Test Case] + + * compile a program using cxx11 e.g. using boost libraries + + [Regression Potential] + + * llvm-3.4 is a compiler, and the change should affect only cxx11 + support (since the library is ABI compatible). + + So, fixing cxx11 support shouln't have any regression, only the feature + will start working, while it wasn't before + + [Other Info] + + * Doko ack'd the SRU, and it should be the best voice here, for sure better than mine :) + + This packages does not contain any __cxx11 symbols when installed. This causes the problem that user-space applications cannot link successfully to it. Recompile the (untouched) dpkg source package on the same machine and installing it solved the problem. There seems something in the package generation broken.
