Package: lgeneral Version: 1.2.3+dfsg-1 Usertags: goto-cc Tags: upstream During a rebuild of all packages in a clean sid chroot (and cowbuilder+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.
