--- Comment #10 from Jiri Danek <jdanek at redhat dot com> ---
I am trying to compile qpid-proton with gcc snapshot (again in docker,
https://hub.docker.com/r/jdanekrh/nightly-gccgo-trunk-docker-image/) and as far
as I can tell, the go binding package does compile successfully. So I'd say
this bug is resolved.

What _does_ fail though is compilation of the go sample program which uses the
binding package. It is quite likely this is a bug in the build script which was
never before tested with gccgo.

FYI, the compilation error when compiling the sample program
