-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gcc-4.8 in Ubuntu. https://bugs.launchpad.net/bugs/1360404 Title: -dumpversion output inconsistent with upstream Status in “gcc-4.6” package in Ubuntu: New Status in “gcc-4.7” package in Ubuntu: New Status in “gcc-4.8” package in Ubuntu: New Bug description: Note: this bug also affects gcc-4.6, gcc-4.7, gcc-4.8, and possibly gcc-4.9 Sometime between gcc-4.5.8 and gcc-4.6.3 debian (accidentally) changed the output of the -dumpversion flag; possibly in an attempt to fix this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=643891 As a result, -dumpversion now reports MAJOR.MINOR version info. This is in contrast to upstream and other distributions of gcc which report MAJOR.MINOR.PATCH version info. This prevents simple machine parsing of gcc/g++/gfortran versions to filter out misbehaving versions. (For instance gcc-4.7.0's and gcc-4.7.1's C++11 ABI incompatibilities.) This bug has trickled down through gcc-4.6, gcc-4.7, gcc-4.8, and possibly gcc-4.9, and affects their binary packages (gcc, g++, gfortran, others?). This bug can be fixed by applying the attached patch, after "debian patching".
