Latest CVS updated last night. Make a new standard forum in a course set to use no groups, with forum also set to no groups. Teacher posts a discussion and the students can't see it, just getting a message saying there are no posts available. With debugging turned on to max, this error comes up:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 1210156000) OR d.userid = 1871) ' at line 8
