The compiler generates duplicated symbols for "my_array" in the following code snippet and causes the linker to fail. The issue is triggered by the circular reference in line 18 (which is perfectly legal btw). Commenting that line and the error goes away. This issue is present in 2.071.1 on OSX and windows at least, but not present in version 2.067.1, at least not in OSX or linux. 01 struct Foo { 02 int a; 03 immutable(Foo[])* b; 04 this(int _a, immutable(Foo[])* _b) 05 { 06 a = _a; 07 b = _b; 08 } 09 this(int _a) 10 { 11 this(_a, null); 12 } 13 }; 14 15 immutable Foo[] my_array = [ 16 Foo(1), 17 Foo(2), 18 Foo(3, &my_array), 19 ]; 20 21 void main() 22 { 23 int a = my_array[0].a; 24 }
Hello, I tested the code snippet with dmd-2.072.0 under Linux64bit and the problem is gone (it was still present with dmd-2.071.2). Even though this bug report was never addressed. I will test it under windows and and MacOS asap and will update this report accordingly. JLima
Just tested on Windows with git HEAD and the issue is still present. On Ubuntu 16.04 the issue is not present. Changing description to Windows

Changing description to Windows I tested before with release 2.072.0 and the problem was fixed. See my previous comment from 2016-11-25. However. at the time, I didn't check on all platforms Triggered by your comment, I tested now the release 2.076.1 on the following platforms Ubuntu 16.04 64bit: passed OS X 10.10: passed Windows 10 64bit: failed but due to a different issue. See below. > dmd snippet.d OPTLINK (R) for Win32 Release 8.00.17 Copyright (C) Digital Mars 1989-2013 All rights reserved. http://www.digitalmars.com/ctg/optlink.html teste.obj(teste) Offset 00370H Record Type 009D Error 16: Index Range Error: linker exited with status 1 I noticed OPTLINK is for Win32. Weird! So I passed the option -m64 to dmd to force it to use the microsoft linker. > dmd -m64 snippet.d And it compiled the snippet without errors. So I would say this problem seems to be fixed!

Cool! I had the same error weird error and I thought that was the issue. Thanks a lot. Closing as fixed
