This function: 

void bar (void)
{
  int a;
}

when compiled with g++
is dumped as: 

;; Function void bar() (_Z3barv)
;; enabled by -tree-original

{
   { // extra block, should not be needed
      int a
   } 
}

when compiled with gcc 

;; Function bar (bar)
;; enabled by -tree-original

{
   int a
}


The extra blocks created are also confirmed by -fmem-report:
for gcc:
blocks                     3        132
for g++:
blocks                     5        220
