I think the bison version was misleading. I was attempting to fix the errors on our internal CI setup but changing bison didn't seem to help. I'm still quite perplexed as to what is going on and why the failures originally disappeared.

I am unable to reproduce these results and still have 9 failures on trunk (ubuntu 12.04).

Interestingly, I just ran the test-suite without lnt. Here I get an entirely different set of failures.
