ah ok, interesting that the bug was kind of erratic. So are you saying
that it will necessarily show up under valgrind if "it needs more work"?
If yes, I could try to do that. Or is the issue more subtle?
It's sure to show up under valgrind if it involves reading/writing
off the end of dynamically-allocated memory, which was the case
here. But in fact, after a little more testing I think this is OK
now.
