Confirmed, reduced testcase:
template<typename T> bool cas(const T& test_val) 
{
  bool ret;
  __asm__ ("": :"r"(test_val));
}
struct atomic_ptr         {
  atomic_ptr(){}
  atomic_ptr(const volatile atomic_ptr& a) {  }
};
void pop()
{
  atomic_ptr ne;
  cas(ne);
}

This is invalid code as you are passing a struct to an inline-asm as a register (the code used to use "a" 
constriant but I changed it to a "r" constaint to make it general across targets).
