I was surprised by that statement, so I did some experimentation.
Compiling

struct A{
  ~A();
};

int foo();

int main()
{
  for(int i=0;i<4;i++){
    A a;
    foo();
  }
}

with -O2 -funroll-loops indeed generates duplicate assembler labels on
i586-pc-linux-gnu, due to gcc recycling the assembler labels for the
exception cleanup regions when unrolling.
