             Bug #: 51573
           Summary: [4.7 Regression] ICE (segfault) in
                    lto_varpool_encoder_encode_initializer_p
    Classification: Unclassified

ICE happened during a Firefox build.

 % cat test.ii
extern "C" struct JSObject;

template < class T > class HeapPtr
{
};

struct PendingProxyOperation {
    JSObject *object;
};
struct ThreadData {
    PendingProxyOperation *pendingProxyOperation;
};
struct JSThread {
    ThreadData data;
};
struct JSContext {
    JSThread *thread_;
};
class TypeConstraint
{
    virtual void newObjectState () {
    }
};
class TypeSet
{
    TypeConstraint *constraintList;
};
struct Property {
    TypeSet types;
};
struct Cell {
    Property **propertySet;
};
struct JSObject:Cell {
};
bool
IndexToId ()
{
    return 0;
    bool IndexToIdSlow (JSContext);
}
