Would parse a base length of 0, a exponent length of 32, and an exponent length of `2**256 - 1`, where the base is empty, the exponent is `2**256 - 2` and the modulus is `(2**256 - 3) * 256**(2**256 - 33)` (yes, that's a really big number). It would then immediately fail, as it's not possible to provide enough gas to make that computation.

Would also parse as a base of 3, an exponent of 65535 and a modulus of `2**255`, as it attempts to grab 32 bytes for the modulus starting from 0x80, but then there is no further data so it right pads it with 31 zeroes.
