Package: libdc1394-22 Version: 2.2.2-1 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.

This will ensure the compiler performs appropriate conversion or promotion, which may differ from that towards an unsigned. Best, Michael
