C#-v3.7.4 and NEOGO-0.106.1 calling result mismatch

[dusmart]

Between testnet C# v3.7.4 and golang NEO-GO:0.106.1. The calling results of AoAaBgABLAESwB8MBG1haW4MFFMo9Cc1/EJCiUOG1Ow0/ZfStZoXQWJ9W1I= differ.

Current Behavior

FAULT

Expected Behavior

HALT as what C# did

Possible Solution

I have no idea.

Steps to Reproduce

curl -sd '{ "jsonrpc": "2.0", "id": 5, "method": "invokescript", "params": ["AoAaBgABLAESwB8MBG1haW4MFFMo9Cc1/EJCiUOG1Ow0/ZfStZoXQWJ9W1I="] }' https://rpc.t5.n3.nspcc.ru:20331/ > /tmp/result_neogo.json

Context

neo-project/neo#3296

Your Environment

• C# v3.7.4
• golang NEO-GO:0.106.1

As public accessible testnet C# nodes are not available for now. You may have to run you own local nodes. From the comparison of neogo's gas_consumed and c#'s, I guess that neogo is more strict than C#.

I'm not sure which one should be changed. As C# is now the mainstream on mainnet, I guess that we'd better adapt neogo to C#'s behavior.

Maybe it should be fixed by C#.

We'll check, but at instruction 177 (SYSCALL): stack is too big / json error: too big: size is somewhat inspiring in this case.
