D sınıfı üyelere erişim neden OSX'de kilitleniyor?

Question

Projelerimden birinde beklenmedik segment hataları yaşadıktan sonra yeni bir tane yaptım.

dub init crashtest

Sonra ben yazdım:

import std.stdio; 

class testing 
{ 
    void init() 
    {} 
} 
void main() 
{ 
    testing one; 
    one.init(); 
    writeln("Edit source/app.d to start your project."); 
} 

segfault one.init geliyormuş gibi görünüyor(). Temel olarak, sınıf işlevlerini çağırmak onu tetikler. Ama neden?

Birkaç dakika harcadım 'writefln ("test"); program boyunca. Kod, init fonksiyonuna asla ulaşmaz. Init() 'de hiçbir kod yürütülmez.
