[Bug libstdc++/38684] New: [c++0x] ICE using initializer_list ctor in derived class

[cfairles at gcc dot gnu dot org]

#include <initializer_list>

struct Y {};

template<class T> struct X : Y { 
  X(std::initializer_list<T>) {}
}; 

struct A { 
  X<int> v;
};

int main() {
  A a{ {1,2,3} };
}

Compiling with -std=c++0x gives:
internal compiler error: in process_init_constructor_record, at
cp/typeck2.c:987

This compiles w/o ice or error if X does not derive from Y.

------- Comment #1 from pinskia at gcc dot gnu dot org  2008-12-31 20:54 -------
Confirmed.

986       gcc_assert (!TYPE_BINFO (type)
987                   || !BINFO_N_BASE_BINFOS (TYPE_BINFO (type)));


The assert looks wrong for C++0x code.

------- Comment #3 from cfairles at gcc dot gnu dot org  2009-01-01 02:28 -------
Templates aren't required, slightly reduced testcase:

#include <initializer_list>

struct Y {};

struct X : Y { 
  X(std::initializer_list<int>) {}
}; 

struct A { 
  X v;
};

int main() {
  A a{ {1,2,3} };
}
