Comment 14 for bug 581525

Alright I think I have finally tracked this one down, and we should have some packages for testing soon. This is a user space fix to make the table actually work but will also get a kernel side test to ensure the table is properly bounded at load time.

What is happening is the created dfa is not being properly padded on the one side of the table, so that indexing can reference memory outside the bounds of the table. This is pretty much limited to the small profile with regex dfas.
