No, bug 1382 is still open. Some cases of it have been fixed (eg, the one in
comment 4). I'm not sure why this particular case is so bad, I'll take a look
at it when I get a chance.
Note that CTFE still uses copy-on-write for values, and no memory is ever
released (this is more general than bug 1382). My guess is that the code below
just runs for a very long time.
