--- Comment #1 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-08-31 13:07:54 UTC ---
This is what Creduce came up with:
typedef bool (*IsAcceptableThis)(const int& v);
typedef bool (*NativeImpl)(int *, int);
template<IsAcceptableThis, NativeImpl>void CallNonGenericMethod();
typedef int (*JSNative)(int *, unsigned, int *);
struct A
{};
class B : A {
static bool is(const int& p1);
template<int(B&)>static bool getterImpl(int *,
int);
template<int(B&)>static int getter(int *,
unsigned,
int *);
template<int(B&)>static bool defineGetter();
static int byteOffsetValue(B&);
A * initClass();
};
A *js_NewFunction(JSNative);
template<int
ValueGetter(B&)>int
B::getter(int *, unsigned, int *)
{
CallNonGenericMethod<is, getterImpl<ValueGetter> >();
}
template<int
ValueGetter(B&)>
bool
B::defineGetter()
{
A *a = js_NewFunction(B::getter<ValueGetter>);
}
A *
B::initClass()
{
defineGetter<byteOffsetValue>;
}

Adding Jason in CC, looks like this is related to the recent SFINAE work...

Further reduced:
