Coffeescript test suite errors after parser build?

[GabrielRatener]

When forking coffeescript, I run $ cake test, with all but 3 tests passing. But after running

$ cake build
$ cake build:parser
$ cake test

with no modifications, 9 tests fail. Is there something I am doing wrong or is this a bug?

[jashkenas]

Perhaps you have a newer version of Jison installed? And we need to update?

Can you investigate the nature of the errors?

Here is the output from the tests:
