Here are some preliminary results of a test rebuild on x86_64-linux-gnu with trunk 20140118, for all 10755 source packages building architecture dependent binary packages. Compared to the current gcc-4.8 in Debian unstable, there were 103 new build failures. The gcc-4.9 packages used can be found in Debian experimental (apt-get -t experimental install g++ g++-4.9). Binutils 2.24 branch was used, and glibc-2.17. The only changed components in the test rebuild were the binary packages produced by the gcc-4.9 source package.
The build logs for the builds failing with 4.9 but succeeding with 4.8 can be found at http://people.debian.org/~doko/tmp/logs-20140122/ - filed issues for GCC after reproducing ICE's with trunk 20140122. 59917, 59918, 59918, 59920, 59924, 59925, 59927. - There are 13 packages failing with link errors, all C++ related, and many of these with undefined references to vtables. - There are 9 packages with test failures, the most prominent ones perl, pcre3 and mysql-5.5 (see below). The following build failures are triggered by the new GCC: - More strict C++, see below for the packages failing with the same error messages. - Some packages fail with -Werror and new warnings. Werror=maybe-uninitialized, -Werror=unused-function - missing symbols in debian symbols files - gfortran module version mismatches. These seem to go away once the dependencies of these packages are rebuilt with the new gfortran. Planning to do the same for arm-linux-gnueabihf as soon as 59913 is fixed. Thanks to David Suarez for actually doing the test rebuild.
