Yep. It is still there in 15w46a https://www.youtube.com/watch?v=YbLsUN94fQ8&feature=youtu.be

Comment by Kumasasa [ 14/Nov/15 ]

Is this still an issue in the current Minecraft Snapshot 15w45b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

It is still in the latest prerelease 3 .. Here is a video: http://youtu.be/DvdeNR15hv8

Easy fix: Move the corner.

Comment by Kumasasa [ 17/Mar/13 ]

Not only the blocks inside of the corner trigger the explosion, also blocks outside. See MC-12191

Comment by Oscar Parker [ 17/Jan/13 ]

So pretty much the hitbox of the TNT cart intersects the wool block at a corner (not a surprise there, as they turn diagonally). Either the cart hitbox could be made smaller, or stronger checking for a detonation trigger could be implemented.

Comment by Yang.H [ 15/Jan/13 ]

Lava column also detonates. (with damaging cart motion) but water column does not detonates the cart.

Comment by Jared Jeyaretnam [ 14/Jan/13 ]

I think maybe TNT minecarts are meant to detonate if they hit blocks, but these are wrongly intersecting with blocks when they shouldn't be. I wonder what happens if you replace the block with a column of lava? That should detonate it but not normal blocks.
