--- Comment #8 from Roman Kononov <roman at binarylife dot net> 2012-05-21 21:00:42 UTC ---
Another test case (without vectors):

$ cat test.cpp 
void gg();
static __typeof(gg) __gthrw_gg __attribute__((__weakref__("gg")));

template<typename R,typename... A>
struct data {
  template<typename Y,typename X>
  data(Y& y,R(X::*f)(A...));
};

template<typename Y,typename X,typename R,typename... A>
data<R,A...> make_data(Y& y,R(X::*f)(A...)) {
  return data<R,A...>(y,f);
}

void global(data<void>);

struct test {
  void bar() {}
  void doit() { global(make_data(*this,&test::bar)); }
};

$ g++ -std=c++11 -c test.cpp 
test.cpp:20:2: internal compiler error: vector VEC(ipa_ref_ptr,base) index
domain error, in ipa_remove_reference at ipa-ref.c:84
 };
