Package: nethack
Version: 3.4.3-15
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 will result in undefined behaviour in at least one of the two following
ways:
- A value greater than 127 is passed in;
- big endian systems will fail to pick the right byte, even if all values are
below 127.

At least now, in 2022, nethack builds fine, so closing this bug.
Looking at the buildds in 2014, it generally built there too, so I guess this
was some kind of fluke.
Lets close this bug to keep the BTS tidy :)
