Package: gupnp-tools Version: 0.8.9-1 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.

Reviewing the code, it is not only the declaration that lacks this, but so do all calls to create_item. Hence stack underflow will occur, and undefined behaviour will result (the pointer will take an arbitrary value). Best, Michael
