Target Milestone: ---
code file test.cc:
=============================
class A {
public:
A(int i): i(i){}
int get() {return i;}
private:
int i{0};
};
void func() {
typedef int (A::*f)();
f fs[] = {&A::get};
A *a = new A{1};
for (int i = 0; i < 1; ++i) {
(a->*fs[i])();
}
delete a;
}
int main() {
func();
return 0;
}
===============
envirment: gcc10.4
g++ -fsanitize=address -fsanitize=undefined -std=c++17 test.cc
./a.out
runtime error: index 4198816 out of bounds for type func[1]

Can't reproduce this, neither with 10, 11, 12 nor 2022-08-25ish trunk nor
