Not for me:

bash-3.2$ dmd | head -1
DMD64 D Compiler v2.065
bash-3.2$ dmd -lib foo/traits.d foo/file.d -ofmylib
bash-3.2$ dmd -run main.d mylib.a
Undefined symbols for architecture x86_64:
  "_D3foo4file1F6__ctorMFNciZS3foo4file1F", referenced from:
      __Dmain in main.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
--- errorlevel 1

Please provide a test case which works in 2.065 but not in master or the RC.

I don't know how you got the impression that we made the conclusion based on whether something "has been broken for a while in trunck".

No, that's not right. I was trying different things but this is clearly wrong. But the point stands:

bash-3.2$ dmd main.d mylib.a
Undefined symbols for architecture x86_64:

"_D3foo6traits32__T10lvalueInitTS3foo4file4ImplZ10lvalueInityS3foo4file4Impl",
referenced from:
      _D3foo4file1F6__ctorMFNciZS3foo4file1F in mylib.a(file_3_46.o)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
--- errorlevel 1

I did some investigation and I have better:

The problem is due to an update in OSX's linker. That indeed not a regression( not a DMD regression anyway). That is why is is now failing with previous version of DMD as well.

LLVM had a recent update to fix this, but I can't find the commit that did it.
