--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
It's not calling the wrong constructor, GCC is just making a trivial copy of
the object (without using any constructor) for the second operand of the ?:
expression. That is never constructed using a constructor, but it is destroyed,
which causes the double free.
;; Function main (main, funcdef_no=14, decl_uid=2419, cgraph_uid=15,
symbol_order=14) (executed once)
int main ()
{
struct A D.2421;
struct A D.2423;
void * _8;
<bb 2> [local count: 1073741824]:
D.2421 ={v} {CLOBBER};
_8 = operator new (4);
MEM[(int *)_8] = 42;
D.2421.a = _8;
__builtin_printf ("C %p\n", &D.2421);
D.2423 = D.2421;
A::~A (&D.2423);
D.2423 ={v} {CLOBBER};
A::~A (&D.2421);
D.2421 ={v} {CLOBBER};
return 0;
}

Or by r13-2963-g32b2eb59fb9049 .
Anyways both together are needed IIRC.
