System Error when running Ganache 2.0.0 on darwin (ABIEncoderV2)

This error happened in two cases:

• when I wanted to look at a contract that uses ABIEncoderV2 features - structs as inputs in external/public functions
• when I wanted to look at a transaction that contains calls to public functions with structs as inputs

Using solc 0.5.7

PLATFORM: darwin GANACHE VERSION: 2.0.0

@haltman-at , I was running this run function here: https://github.com/ctzurcanu/dType/blob/242edbb518c59362fb69cb3a387bbe3d87575ba0/contracts/contracts/dType.sol#L259

The contracts are wrapped in a truffle project: https://github.com/ctzurcanu/dType#contracts
