Looks like it is still not fixed in the end:

The patch which hit the problem just added unrelated builtins even.

I can still reproduce it with trunk from 2009-02-07 (updated after your
comment).

As mentioned before the testcase is a little fragile. Some weeks ago I had a
much larger testcase (about 150 lines) which I couldn't reduce any further. To
me this looks like some fishy memory access.
