There is currently not much we can do about this. Previously our regexp engine just crashed or reported no matches, without signaling there is something wrong. So behaviour in FF28 is also incorrect!

Now there is improvement coming! Hopefully in FF31 we will have the same regexp jit as chrome. So we will be able to run those regexp, without reporting an error.
