Package: emoslib Version: 000392+dfsg.1-2 Usertags: goto-cc 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.
