The dynamic library.so is built from D (with pyd), and invoked
from Python.
I'm just wondering How to debug/set breakpoint a dynamic

Can someone give an example?

If I run L64 alone (without L66 ~ 79 grpc-d part):
```
64: auto t = new Thread({fun();}).start();
```
it works fine.

Because of this the offsets are wrong. So you wouldn't be
