How to reproduce:
Run the following Command:
/summon FallingSand ~ ~5 ~ {Block:minecraft:command_block, TileEntityData:{auto:1b, Command:/say HI}}
What I expected:
The Command Block will say HI upon touching the ground.
What actually happened:
The Command Block din't do anything.
(I'm not sure if this is a bug, but it seems to me like that.)

But while the Command Block is falling, it cannot execute the command, because it is an Entity. I am going to try this with /setblock soon.
FYI: MC-31100 and related tickets.
This is not a bug; WAI. 'being' auto:1b doesn't cause a command block to activate, it's the change from auto:0b to auto:1b that does it.
