Package: filtergen Version: 0.12.4-5.1 Severity: wishlist Usertags: goto-cc
During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder and pbuilder) the build failed with the following error. Please note that we use our research compiler tool-chain (using tools from the cbmc package), which permits extended reporting on type inconsistencies at link time.

Amending this will make sure no one ever uses the non-existent return value. Best, Michael
