Package: cups-filters Version: 1.0.53-1 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.

For any platform with sizeof(unsigned long) > sizeof(int), such as amd64, the high bytes of startpos will take an arbitrary value. If the semantics of startpos is what its name suggests, it may be worth raising the severity of this bug report (if not tagging it security). Best, Michael
