Package: dcfldd Version: 1.3.4.1-2.1 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.

Depending on assumptions and guarantees provided by the code elsewhere this may or may not cause errors. In either case, fixing the declaration in util.h to match the definition will enable the compiler to provide more meaningful warnings in case these are due. Best, Michael
