Ok, after dustmite and a little manual cleaning:

//thread.d
class ThreadError : Error
{
    this(string )
    {
        super(msg, file, line);
    }
}

void onThreadError() {
    __gshared ThreadError = new ThreadError(null);
}

If I comment out the super line, I get

super() call in constructor
     this(string )
     ^

instead. The compiler hangs there and Ctrl-c was required.
