Hi! Thanks a lot for bringing up this issue. I discovered that the problem is because we're using an incorrect length when writing to the limitBuffer.

https://github.com/KusionStack/kclvm-go/blob/f2813c3b3e867910a44bd251fa6d1a400cc8e8e1/pkg/kclvm_runtime/proc.go#L112

I will make a pr to fix it soon
