That's what I was afraid of. Well, some shotgun-debugging later, I found
the problem. A "+1" that should be "+2" because UTF-16 is two-byte... As
the data is freed very soon afterwards this didn't cause a crash, but I
bet it would've given the same warning if it was run on FreeBSD with
debugging and asserts enabled.

Anyway. Thanks, got it sorted.
