Package: jpnevulator Version: 2.1.1-1 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 short) < sizeof(int), the high bytes of size will take an arbitrary value. Best, Michael
