Lines 2091 to 2095 in 0f37d6b

	// accounts[0] can be either Account or Mint based on its data_len
	// accounts[1] is Authority
	// Note: We cannot determine the type at compile time, so we call both cheatcodes
	cheatcode_is_account(&accounts[0]); // Could be Account
	cheatcode_is_mint(&accounts[0]); // Could be Mint

Cheatcodes are mutually exclusive because they mutate the stored data according to which object is referred to (Account, Mint, Rent, Multisig). Therefore we cannot run a test that would branch on which kind of object we have.
According to the comment, the data_len field is used to determine whether a Mint or an Account is present in this test, we will have to split the test.

Fixed in #40 , splitting the proof.
