Comment 1:

Could you please send the output of bison --version?
It looks like the parser is behaving differently than it
usually does.
Thanks.

% bison --version
bison++ Version 1.21.9-1, adapted from GNU bison by coetmeur@icdc.fr

Comment 3:

The Go build requires bison, not bison++.
Did you install bison++ (as opposed to bison) intentionally?
If not, you could try removing bison++ and installing 
ordinary bison.  Or you could ignore the fact that these
tests are failing and use Go anyway, hoping that only
the syntax error cases differ between bison++ and bison.
If you run a build using plain bison, this will work fine.
Thanks for the report.

Status changed to WontFix.

Comment 4 by bortzmeyer:

OK, I was not even aware of the difference between bison and bison++. For me, the
later was simply a more recent version. I 'aptitude installed bison' and now
everything works:
% ./8.out 
hello, world
One more item for the FAQ :-)
