Reduced to:
struct A
{ A(); ~A(); };
A a;
extern "C" { void* __dso_handle __attribute__ ((__weak__)); }
void f()
{ __dso_handle = 0; }
Note the code it self is not right for what you want to do, instead it should be:
extern void* __dso_handle __attribute__ ((__weak__));
But the C++ front-end should be picking up the user variable and not making a new one.

Using Phil's regression hunter (the hard way)
between 2004-07-29 and 2004-07-30 is when this broke.
Caused most likely by:
2004-07-29 Mark Mitchell <mark@codesourcery.com>
* cp-tree.h (IDENTIFIER_REPO_CHOSEN): Define.
(lang_decl_flags): Narrow the width of "languages". Add
repo_available_p.
(DECL_NEEDED_P): Remove.
(FOR_EACH_CLONE): New macro.
(DECL_REPO_AVAILABLE_P): Likewise.
(DECL_TINFO_P): Likewise.
(set_linkage_according_to_type): Declare.
(import_export_vtable): Remove.
(import_export_tinfo): Likewise.

First, I am not sure that I agree that this is a bug: __dso_handle is a magic
variable outside the user's namespace.
Second, I cannot reproduce this bug with today's compiler on i686-pc-linux-gnu
using the reduced test case.

I still can reproduce it on the mainline (note that you have to have --enable-__cxa_atexit enabled):
.type __dso_handle, @object
.size __dso_handle, 4
__dso_handle:
.zero 4
.weak __dso_handle
.align 4
.type __dso_handle, @object
.size __dso_handle, 4
__dso_handle:
.zero 4
Still this is a QOI issue, if we do anything we should warn or error out on this situation.
