Thanks, that was helpful. ... Huh. Rebuilding openssl_1.0.2d-1 with gcc-4.9 and using it to build mumble_1.2.10-2 with g++-5, the result works fine. So it seems it was simply the switch to gcc-5 that changed this behavior. On the one hand one could call this a regression since it breaks something that worked before, and on the other hand it caught a bug in the code in mumble that nobody knew it had. This therefore leaves a question as to whether to consider this is a bug or a feature of gcc-5. Probably both. I'm attaching patches for the changes I made to the package files (except the debian/changelog entry simply to up the version number) in case someone wants to repeat the test. -- Chris -- Chris Knadle [email protected]
