Package: openjdk-8
Version: 8u45-b14-2
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.

For all platforms with sizeof(int)<sizeof(long) undefined behaviour will appear
in (at least) one of two ways: either the value will be padded with arbitrarily
valued bits, or the wrong set of bytes will be extracted, depending on
endianness.

Adjusting the declaration in XToolkit.c should solve the problem.
