g++-4.9.0 returned same message.

Created attachment 32772 [details]
Test code using report

1) The problem also exists in gcc 4.10 trunk

2) As written, the presented code would be ill-formed anyway. The following transformed example presents valid code that produces the same ICE:

//-----------------------
struct Base
{
  virtual int b() const{return 1;};
};
   
struct Super:Base{};
 
int main()
{
  constexpr Super s = Super();
  [&]{s.b();}();
}
//-----------------------

I could not reproduce the error, the output looks correct on trunk

No, I can still reproduce the ICE in make_decl_rtl, at varasm.c:1297

below also doesn't work
struct A
{
	int funcA(){return 0;}
};
template<class>
struct B:virtual public A{
	void funcB(){
		[a=this->funcA()]{};
	}
};

int main()
{
	B<A> b;
	b.funcB();
	return 0;
}

仮想継承の時もエラーになるみたいですね。

To save some clicking, Google translate said:

"It seems to be an error even when the virtual inheritance."

right.
i don't know why, but template<class> is also needed, to invoke the error.

Since 5.2.0 we accept the snippet in Comment 3, since 6.1.0 the snippet in Comment 6, thus I'm going to add to the testsuite both anyway. However, we also accept the original snippet, thus I'm keeping the bug open as accepts-invalid.
