Bug after update to 2.072?

[Alex via Digitalmars-d-learn]

Ok, ok. Here, I pasted the code, minimized as far as I could. 
There are 434 lines of code, sorry.
http://pastebin.com/UcZUc79g

The main is empty. This is intended. I still have the 
segmentation fault.

Maybe, I have another hint:
If I comment all the attributes in the
private HeadUnshared!(T) atomicFetchAdd(T, V1)( ref shared T val, 
V1 mod ) //pure nothrow @nogc @trusted
method in atomic.d, in line 657, away, and add something like
import std.stdio;
writeln("kuku");
at the first lines of the body
I get an error message on compiling:

Maybe, this doesn't say anything about the segmentation error. 
But the last two lines are, maybe a hint, which route is taken on 
compilation.
