Package: asn1c Version: 0.9.24+dfsg-1 Severity: wishlist 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.

This leads to interesting constructions such as this one here: http://sources.debian.net/src/asn1c/0.9.24+dfsg-1/libasn1parser/asn1p_y.c?hl=1843#L1843 Cleaning up these declarations will make sure the compiler provides appropriate diagnostics to warn about invalid memory access.
