Reduced testcase:
namespace std
{
template <class T1, class T2>
struct pair
{
T1 first;
T2 second;
};
template <class T>
struct initializer_list
{
};
template <typename T1, typename T2>
struct map
{
map () {}
map (initializer_list <pair <T1, T2>> l) {}
};
}
template <class T>
void
foo (T &p)
{
p.v = { { 0, { .a = 0, .b = 1 } } };
}
int
main ()
{
struct { struct A { int a, b; }; std::map <int, A> v; } p;
foo (p);
}
Started to ICE with http://gcc.gnu.org/r176530 .

lookup_field_1 instead of IDENTIFIER_NODE gets the error_mark_node, and the
following assert chokes on it:
gcc_assert (identifier_p (name));
It seems that if we just return NULL_TREE in that case, everything is fine.
