Package: r-cran-xts Version: 0.9-7-1 Usertags: goto-cc During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder and 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.

Doing a quick codesearch it seems a larger code review is required to establish and fix all these cases. Best, Michael
