> If we strip debug info to another file, BE could not print stack trace
line number during Core. And if we use exception as error handling mechanism
the line number is also lost.
> Even though strip debug info to another file will reduce the binary size,
I think maybe we could implement it in the future because more debug info will
help us fix bugs more quickly.

tool?
It is ok that we can still see the error stack in `be.out`, just like before:
```

```
I am not sure about the exception mechanism. And because when we do binary
release, it is hard to push a large file to
Apache SVN.
