Chances are, this could be totally intentional on Mojang's part, but I'll report it just in case. I couldn't find any other issues about this.
I'm working on a resource pack, but after updating it to 1.9, I noticed it's cracks had gone all out of whack.
This only happens to blocks, though, where the texture I used was a 64*64 image. It's a bit hard to explain.
CraftingTable.png is the image the the model uses in-game. All of the textures for the crafting table are in that 64*64 image, and each quadrant of the image is a different side.
2016-03-12_14.34.33.png shows the effect the texture mapping has on the block. The cracks are too large, and abide to CraftingTable.png rather than the block model.
