[Docker-maint] Bug#748041: Conflicting declarations of function lookup

[Michael Tautschnig]

Package: golang
Version: 2:1.2.1-2
Usertags: goto-cc

During a rebuild of all packages in a clean sid chroot (and cowbuilder+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.

Given that the signatures differ both in the number of parameters and the return
type, quite likely this conflict is not at all intended. Is there a "static"
missing?

Best,
Michael
