run script
Compiling the code below with -fblocks causes clang to trigger it's own
assertion. The run script is attached as requested, the preprocessed source
code looks identical to the code below.
[ --- code --- ]
typedef void (^Block)();
void invoke_block (Block block);
// --- a class
class A
{
public:
int f () { return 0; }
};
// --- template base class ---
template<class T>
class Base
{
public:
T * t;
virtual void virtual_function () {}
};
// --- derive from template base class
template<class T>
class Derv : public Base<T>
{
virtual void virtual_function ();
};
template<class T>
void Derv<T>::virtual_function ()
{
invoke_block (^() {
int i = Base<T>::t->f ();
});
}
int main(int argc, char **argv)
{
Derv<A> d;
return 0;
}
