Package: blktap Version: 2.0.90-2 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.
