Can it be repeated:

1. Get an RfTools builder, shape card, a Jabba barrel, and a power source for the builder (for testing, I used a creative EIO capacitor).
2. Place the builder with the Jabba barrel on top of it and the power source connected.
3. Configure and select a nearby area of the world with the shape card and then put it in the builder.
   • I tested box, solid box, and bottom dome modes of the shape card.
4. Fill the barrel to at least 63 stacks + 1 of a block (ex dirt).
   • Crash doesn't happen if there's just 63 stacks (or less).
   • Upgraded barrels appear to follow the pattern of crashing when there is less than one stack of space remaining (ex, for a barrel with a single storage upgrade, 127 stacks + 1 will crash).
5. Apply a redstone signal to the builder to start building. This is where it crashes.

Known Fix:
As a workaround, ensuring there's always at least a full stack of remaining storage in the barrel should avoid the crash (ex, for a default barrel, having no more than 63 full stacks of blocks in the barrel).

This is a vanilla RFTools bug I think I reported at least some months back, maybe even more than half a year to McJty.
