How to collect more info when crash happen?

[oatgnauh]

Our application has many users, so we need to monitor the crash rate to ensure stable iterations. Currently, when a crash occurs, we can only collect the stack information of the current thread and related logs.
However, this cannot solve all scenarios. For some crashes, such as those caused by wild pointers, the stack does not have much guiding significance.
In addition, there is another type of crash I encountered, where the error message is only a simple description such as worker sent an error!undefined,undefined: undefined, and it is impossible to locate where the problem is.
So my request is:

1. It is necessary to be able to collect the stack and corresponding register information of all threads
2. There is a corresponding interpretation tool

I collect crash stack by modify handleMessage in .worker.mjs, with try .. catch(ex)
