"Somebody" here...
I've never been convinced that I understood what was going on with Tigran's problem. I'm particularly bothered by his temp fix, which, afaik, should have been a nop.
From previous Tigran posts:

The only odd thing is that length 0 region at the end, which my patch will stomp all over, but I can't see in current code that it should matter. Or did I miss a fencepost?

Well, I'd put a patch in, but someone else wants to take over the memory detection stuff so I'm not sure if our patches would collide with each other or not.
