Sorry, this was not affront, it was meant as my POV that you may 
have problems to get my problem because I have (as usually) 
forgot to make this more visible that some code was truncated.

I tried your suggestion, as replied to Adam - the symbol is 
unique and it shows that correct location. It's not different 
from the error message.

However, this error has nothing to do with `assert()`. In fact 
the compiler allows nothing than invocation or this error will be 
triggered. Even that fails:

```d
// same error:
auto test = cast(void*)fun;
```
