--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
Probably duplicate test-case for C++:
template <class T> class A
{
public:
operator bool ();
T *operator-> ();
template <class U> A<U> m_fn1 ();
T *d;
};
class B
{
public:
typedef A<B> Ptr;
};
template <typename T> T constant_value (long long *);
class C
{
public:
typedef A<C> Ptr;
long long value___trans_tmp_1_0;
template <class ValueType>
ValueType
m_fn2 ()
{
return constant_value<float> (&value___trans_tmp_1_0);
}
};
class D
{
B::Ptr m_lastType;
void m_fn3 ();
};
void
D::m_fn3 ()
{
B::Ptr conditionType, leftType;
if (C::Ptr condition = conditionType.m_fn1<C> ())
if (condition->m_fn2<unsigned long> ())
m_lastType = leftType;
}
