- 0x11: If an arithmetic operation results in underflow or overflow outside of an

- 0x31: If you call
.pop() on an empty array.
- 0x32: If you access an array,
bytesN or an array slice at an out-of-bounds or negative index (i.e. x[i] where i >= x.length or i < 0).

- 0x51: If you call a zero-initialized variable of internal function type.
