Referring to an object outside of its lifetime.

[h0nzZik]

This program,

int main() {
	int *p;
	{
		int x = 1;
		p = &x;
	}
	(*p)--;
}

when compiled as a C program, prints the message:

out-of-scope.c:7:3: warning: Referring to an object outside of its lifetime. (Undefined behavior)

However, when compiled as a C++ program, no error is printed and it gets stuck with

`readBytes-aux(_,_,_,_)_CPP-EXECUTION-IO`(loc(obj(#token("4","Int"),#token("4","Int"),auto(#token("0    ","Int"))),#token("3","Int")),#token("4","Int"),`.List`(.KList),tcpp(quals(`.Set`(.KList)),`.Set`(.K    List),`int_CPP-TYPING-SYNTAX`(.KList)))

at the top of the k cell.
