Package: canl-c Version: 2.1.2-1 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.

Yet amending the declaration seen by can_ssl.c will certainly help the compiler to provide more meaningful diagnostics. Best, Michael
