I didn't know where environment was for, sorry.
My computer system specs are:
Windows 7 64-bit
16GB RAM
Intel i7 Processor 3.4GHz quad core
Radeon HD 7850 Graphics card
My minecraft uses 512MB of memory (RAM I think).
I'm sorry, but in that bug report it says it crashes their game, for me it doesn't crash as you can see.
That report also doesn't say it moves the direction of the chest or that it disappears with a block update.
I tested this in snapshot 13w01b and I don't see it anymore, even if the tnt doesn't destroy anything within 1 block form the chest (like Richard was talking about). So I guess it's fixed 🙂
