Package: boinc Version: 7.2.42+dfsg-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.

As the actual implementation (in util.c), however, does not return a value, spurious errors will be reported or true errors ignored. Best, Michael
