how to track error location?

[sky_haihai]

I was keeping getting error messages like access violation (address: xxxxxx)
Therefore, I'm wondering how to use that address?

Hi, does it happen every time? Can you tell me what you are doing when it happens?

[sky_haihai]

No, most of the time it happens when a zexpression inside a model trying to read or write some variables outside of the model, which I kinda figured it out after posting this thread. I guess the problem is spawning order or spawning race which leads the zexpression to read a nonexistent variable(my guess )?

Ok . It could also be a bug so if you find something that does not make sense then please let me know so I can fix it.
