Package: libxt Version: 1:1.1.4-1 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.

Having structs of different size is dangerous enough, but here it seems to
highlight that LONG64 is not defined uniformly:
http://sources.debian.net/src/libxt/1:1.1.4-1/include/X11/CallbackI.h?hl=66#L66
As X11 makes heavy use of the macro, several inconsistencies may be hidden here.
Best,
