This is indeed almost certainly the same bug. Here's something smaller: 
----------------------------- 
#include <cstdio> 
 
struct X 
{ 
    X()  { printf ("X::X\n"); } 
    ~X() { printf ("X::~X\n"); } 
}; 
 
void foo (const int i) { 
  X x1, x2; 
  if (i == 1) return; 
  foo (1); 
} 
 
int main () { 
  foo (0); 
} 
------------------------------ 
 
I get 4 calls to the ctor, and 5 to the dtor.
