Here is a small snow arch. New feature or did igloos break?
Nice snow arch.
Comparing it to an igloo's doorframe (image for reference), though, it does seem like just a weird bug.

My guess is that an igloo spawned on the edge of a fresh chunk.
My first mod =D
I recreated the world and I still got this snow arch.
If this ISN'T a bug, it's gotta be Mojang's biggest troll yet. "Yeah here's a new structure for ya. It's a useless arch made of 8 blocks of snow. Have fun."
EDIT: Loaded the world up myself, went to those co-ordinates, and saw one big fat igloo.
Conclusion: 'Tis a bug.
On the note of small partial structures; I would think seeing lumps of blocks would be visually interesting. A mound of dirt and grass, a large "boulder".
