Hi, There was a problem in the conversion of subrs to double-cells, in which the additional cells were not being marked. This was quite a number of commits ago, on master, and having such a large period in which that bug was present is not good for bisection. So I've revived the VM branch. It's the same as master, except commit 325226dad9ab6f0488500e7381a5d1c07dc9ae91 was retroactively introduced in the history.
Anyway, all this to say that VM has been rewritten, and I'd like to copy it over to master. This is fine, but whenever you pull and get a "forced update" you always wonder why that was -- and this is why. If no one objects, I'll forcibly reset master to vm later this evening. Sorry for the confusion. Play around in gitk if it's not clear to you: gitk origin/master...origin/vm All of the merges are from when I was trying to figure out which patch introduced the bug.
