Reduced:

virtual void rp()=0;
void ax(){rp();}
};
struct BLKC
{
virtual void rb(){}
};
template <typename T>
struct LK : BLKC
{
T* p = nullptr;
void rb() override { p->ax();}
};
template <typename>
struct AN : RE
{
void rp() override {}
};
template <const char*>
struct LR
{
virtual ~LR(){}
struct LLC { virtual ~LLC(){} };
LK<AN<LLC>> l;
};
constexpr char ET[]="";
struct I
{

};
int main(){new I();}
