Note the filename in the error message:

   libdep.lib(component_344_d5.obj)

You can also use 'grep' to find all instances and references to
'??1Component@ep@@QEAA@XZ'

Reopened because the fix for Win64 is incomplete.

--- Comment #7 from Manu  ---
I was just doing some work with the latest nightly (should have this patch in
it).
I got a compile error that's new since the last nightly I was using:

3>Building bin\Debug_x64\dplug.dll...
3>libdep.lib(component_344_d5.obj) : fatal error LNK1179: invalid or corrupt
file: duplicate COMDAT '??1Component@ep@@QEAA@XZ'

The project structure is:
  cpplib.lib --+
  dlib.lib |
   |
   dplug.dll

So, cpplib has the stuff I'm extern-ing to, dlib is a binding to cpplib with
some adaptation support code, and dplug is a dll which links both libs.
dlib is mostly extern(C++)'s, and a bunch of extra (mostly extern(D)) code for
adaptation.
I presume that symbol exists in cpplib, but the error suggests that D is also
emitting the same symbol somewhere?


Possibly uninteresting, but I have a lot of code like this:

extern(C++) class CppClass
{
  void cppMethod(ref const(CustomString) );
  void cppMethod2();

extern(D):
  void dAdapterMethod(const(char)[] s) { auto temp = CustomString(s.ptr,
s.length); cppMethod(temp); }
}

This is a simple example, but there's a lot of this going on... so the
extern(C++) classes are kitted out with a bunch of extra functions on the D
side.
I only say this, because I wonder if the fact that I'm not strictly binding,
but also extending may lead to symbols being emitted...

Compilable D version of the code:

  extern (C++)
  {
class Base
{
~this() {}
size_t x = 4;
}

interface Interface
{
int Method();
}

class Derived : Base, Interface
{
size_t y = 5;
int Method() { return 3; }
}
  }

The layout for Win64 Base is:

  4Base6__initZ:
void* 
size_t x;


The layout for Win64 Derived is:

  7Derived6__initZ:
void* 
size_t x;
size_t y;
void* 

These can be figured out by running obj2asm on the object file and looking at
it.
