Yes, makes more sense with the right sources now.
The error may occurred as I re-organized my modules and a type 
became unavailable(?)

The `typeSemantic` function is called with a null-argument indeed:
```d
type = null
loc.filename = "..\dmd2\src\phobos\std\array.d"
```
Something related to `Appender.put!`, to precise this line (3513):
```d
auto bigData = (() @trusted => _data.arr.ptr[0 .. len + 1])();
                ^
```

called from `ForeachType!` and my missing type, I assume. 
Unfortunately, I only see the filename to my source file but 
didn't found out the actual line number of the call yet (The data 
I found hat a 0 line number).
